For the first order reaction
            2N2O5(g) → 4NO2 (g) + O2 (g)
  • a)
    The concentration of the reaction decreases exponentially with time
  • b)
    The half-life of the reaction decreases with increasing concentration of the reactant.
  • 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,D'. Can you explain this answer?

For the first order reaction 2N2O5(g)→ 4NO2 (g) + O2(g)a)The...
→ 4NO2(g) + O2(g), the rate law is:

rate = k[N2O5]^2

where k is the rate constant and [N2O5] is the concentration of N2O5.

This means that the rate of the reaction is directly proportional to the square of the concentration of N2O5. Therefore, if the concentration of N2O5 is doubled, the rate of the reaction will be quadrupled.

The overall order of the reaction is 2, which means that the sum of the exponents of the concentration terms in the rate law is equal to 2. This indicates that the reaction is second order with respect to N2O5.

It is important to note that the rate constant, k, is dependent on temperature and can be determined experimentally. The activation energy of the reaction can also be calculated using the Arrhenius equation.
