For the first order reaction 2N(2)O(5)...

For the first order reaction
`2N_(2)O_(5)(g) rarr 4NO_(2)(g) + O_(2)(g)`

A

The concentration of the reactant decreases exponentially with time.

B

The half life of the reaction decreases with increaisng temperature.

C

The half life of the reaction depends on the initial concentration of the reactant.

D

The reaction proceeds to `99.6%` completion in `8` half. Life durations.

Text Solution

Verified by Experts

The correct Answer is:
A, B, D
`2N_(2)O_(5)(g) rarr O_(2)(g)+4NO_(2)(g)`.
`r = k[N_(2)O_(5)]`
(i) An increaisng temperature, rate of reaction increases Therefore `t_(1//2)` decreases.
(ii) Concentration of `N_(2)O_(5)` decreases exponentially w.r.t. time.
(iii) In `8` half lives, reaction is almost complete, i.e., `99.6%`.
