(f is the focal length, v is the image distance, and u is the object distance)
Chemical formulas are of great significance in BITSAT; most of the numerical problems in Physical Chemistry will either make or mar your performance. Chemistry and both Inorganic and Organic Chemistry in particular will also test you on some principles and reaction mechanisms. Here are some BITSAT Chemistry formulas that will come in handy:
Ideal Gas Equation:
Pressure × Volume equals to number of moles × Gas constant × Temperature
Graham’s Law of Diffusion
According to it "At constant temperature and pressure, the rate of diffusion of a gas is inversely proportional to the square root of its density or molecular weight". It is applicable only at low pressure.
Here r = rate of diffusion or effusion of a gas or liquid. M and d are the molecular weight and density respectively.
For any two gases, the ratio of the rate of diffusion at constant pressure and temperature can be shown as
Hence diffusion or effusion of a gas or gaseous mixture is directly proportional to the pressure difference of the two sides and is inversely proportional to the square root of the gas or mixture effusing or diffusing out.
Some Other Relation Based on Graham’s law
As r = V/t = Volume/time, thus:
Arrhenius Equation:
We know that the first-order equation is given as follows:
But there are other forms of rate law also available that we use for different purposes. These forms are mentioned below:
Use to solve numericals:
Exponential form:
This equation is also known as exponential form.
The rate constant is shown by this formula; Rate constant = Frequency factor × Exponential factor related to activation energy
Boyle’s Law:
k1 is the proportionality constant whose value depends upon the following factors.
Pressure and volume are direct and opposite ratio with temperature remaining constant, that is pressure is inversely proportional to volume of the gas.
Molarity Formula:
Molarity (M) is defined as the number of moles of solute dissolved in one litre (or one cubic decimetre) of solution,
First Law of Thermodynamics:
Heat supplied = Work done by the system + Increase in internal energy
So increase in internal energy = Heat supplied - work done by the system
Nernst Equation:
At T = 298K, the Nernst equation is given as follows:
where n is the number of electrons exchanged.
Thus the Nernst equation for the full cell is given as follows:
It goes without saying that it is possible to solve any Chemistry question with the help of these basic number schemas rather quickly.
Mathematics in BITSAT is more of calculation than application where time plays a key role. There are several mathematical formulas that can be very helpful in solving maths problems and mastering the following BITSAT Maths formulas will go along way in helping you solve problems much simpler.
Quadratic equation:
A polynomial equation in which the highest degree of a variable term is 2 is called quadratic equation.
Standard form of quadratic equation is ax2 + bx + c = 0
Where a, b and c are constants (they may be real or imaginary) and called the coefficients of the equation and (a is also called the leading coefficient).
Eg, -5x2 - 3x + 2 = 0, x2 = 0, (1 + i)x2 - 3x + 2i = 0
As degree of quadratic polynomial is 2, so it always has 2 roots (number of real roots + number of imaginary roots = 2)
The root of the quadratic equation is given by the formula:
Where D is called the discriminant of the quadratic equation, given by ,
Sine Rule
In any ABC, the side are proportional to sines of the opposite angle |
Differential equation:
An equation involving independent variable (x), dependent variable (y) and derivative of dependent variable with respect to independent variable
Integration Formulas:
It is inverse process of differentation.
Probability Formula:
P(A)=Number of favorable outcomesTotal number of outcomesP(A) = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}P(A)=Total number of outcomesNumber of favorable outcomes
Group frequency distribution
Permutations and Combinations:
Permutation basically means the arrangement of things. And when we talk about arrangement then the order becomes important if the things to be arranged are different from each other (when things to be arranged are the same then order doesn’t have any role to play). So in permutations order of objects becomes important.
Arranging n objects in r places (Same as arranging n objects taken r at a time) is equivalent to filling r places from n things.
So the number of ways of arranging n objects taken r at a time = n(n - 1) (n - 2) ... (n - r + 1)
Where
So, the number of ways arranging n different objects taken all at a time = .
Area under a Curve:
A=∫abf(x)dxA = \int_a^b f(x) dxA=∫abf(x)dx
