Most Important Formulas for JEE Chemistry

$$
\begin{aligned}
& \mathrm{c}=\frac{\text { distance }}{\text { time }}=\frac{\text { Wavelength }}{\text { Time Period }}=\frac{\lambda}{\mathrm{T}} \\
& \because \nu=\frac{1}{\mathrm{~T}} \\
& \therefore \mathrm{c}=\nu \times \lambda
\end{aligned}
$$

(i) Work done in reversible isothermal process

$$
\begin{aligned}
& \mathrm{W}=-2.303 \mathrm{nRT} \log _{10} \frac{\mathrm{~V}_2}{\mathrm{~V}_1} \\
& \mathrm{~W}=-2.303 \mathrm{nRT} \log _{10} \frac{\mathrm{P}_1}{\mathrm{P}_2}
\end{aligned}
$$

(ii) Work done in irreversible isothermal process

Work $=-\mathrm{P}_{\text {ext. }}\left(\mathrm{V}_2-\mathrm{V}_1\right)$
That is, Work $=-\mathrm{P} \times \Delta \mathrm{V}$
At $\mathrm{T}=298 \mathrm{~K}$, Nernst equation is given as follows:

$$
\mathrm{E}_{\text {cell }}=\mathrm{E}_{\text {cell }}^{\circ}-\frac{0.059}{\mathrm{n}} \log _{10} \mathrm{Q}
$$


Mass by Volume $\%$ of a component $=\frac{\text { Mass of the component }}{\text { Total volume of solution }} \times 100$
