For the first order reaction
2N2O5(g) → 4NO2(g) + O2(g)
  • 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
Correct answer is option 'A,B,D'. Can you explain this answer?

For first order reaction
[A] = [A]0e–kt
Hence concentration of [NO2] decreases exponentially.
Also, t1/2 =. Which is independent of concentration and t1/2 decreases with the increase of
temperature.
