# NEET Chemistry Chemical Kinetics Questions Solved

For the reaction the concentration of  increases by

Mol $li{t}^{-1}$in 6 second. What will be the rate appearance of$N{O}_{2}$ and the rate of disappearance of ${N}_{2}{O}_{5}$

(B) Rate of reaction= $-\frac{1}{2}\frac{∆\left[{N}_{2}{O}_{5}\right]}{∆t}=\frac{1}{4}\frac{∆\left[N{O}_{2}\right]}{∆t}$

Since $N{O}_{2}$ is the product, therefore, its concentration when t = 0 is zero.

$\therefore$Rate of appearance of $N{O}_{2}$ i.e.

Thus, rate of reaction =

$\therefore$Rate of disappearance of ${N}_{2}{O}_{5}$ i.e.
