Answer to Question #145121 in Molecular Physics | Thermodynamics for Giselle Labagan

Question

1.The half-life for the reactant A in the first order reaction A → B is 36.2 seconds. What is the
rate constant for this reaction at the same temperature?

2. The rate constant for the second order reaction 2NO2 → N2O4 is 2.79 L/mol·min at
48°C. If the initial concentration of NO2 is 1.05 M. What is the half-life?

3. The decomposition of dinitrogen pentoxide obeys the rate-law expression rate = 0.080 min-1
[N2O5].
If the initial concentration of N2O5 is 0.30 M; What is the concentration after 2.6 minutes?
N2O5 → N2O3 + O2

4. A chemical reaction A → B + C is first order in A and has a rate constant of 1.2 x 10-3 min-1
. If
the initial concentration of A is 0.40 M, how much time must pass in order to reduce the concentration of A to 0.22 M
