Question
A second-order-reaction of the type A +2 B→ P was carried out in a
solution that was initially 0.075 mol dm3 in A and 0.030 mol dm3 in B. After
1.0 h the concentration of A had fallen to 0.045 mol dm3. (a) Calculate the
rate constant. (b) What is the half-life of the reactants?
The rate constant for the decomposition of a certain substance is
1.70 x 10-2 dm³ mol-¹ s¹ at 24°C and 2.01 x 10-2 dm³ mol-¹ s¹ at 37°C.
Evaluate the Arrhenius parameters of the reaction.
A reaction 2 AP has a third-order rate law with k = 3.50 x 104 dmº
mol2 s¹. Calculate the time required for the concentration of A to change
from 0.077 mol dm3 to 0.021 mol dm³.
