Question

For the first order reaction
2N2O5 (g) → 4NO2(g) + O2(g)

Options

A.the concentration of the reactant decreases exponentially with time
B.the half-life of the reaction decreases with increasing 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 eight half-life duration

Solution

For first order reaction
[A] = [A]0e-kt
Hence concentration of [NO0] decreases exponentially.Also, t1/2 . Which is independent of concentration and t1/2 decreases with the increase of temperature.

log (2.4) = 8
