Question

What is activation energy? If the rate of decomposition of N_2O_5 in the following reaction at a particular instant is 4.2 times 10^-7 M/s, 2N_3O_5(g) rightarrow 4NO_2 + O_2 a) Write the rate expression of the above equation. b) What is the rate of appearance of a) NO, and b) O_2 at that instant Consider the following reaction Use the above data from table, determine the a) Determine the order of reaction with respect to [A] and [B] and write the rate law for the above reaction. Also write the order of overall reaction.

Explanation / Answer

Q3)

if we double the concentration of A alone from 1.50 t o 3.0

rate also doublled from 0.320 to 0.640

it means with respect to A reaction is first order.

if we double the concentration of B alone from 1.5 to 3.0

rate increases 4 times from 0.32 to 1.28

so with respect to B reaction is second order

overall order = 1 + 2 = 3
