Question

For the reaction A → B, the concentration of A is observed over time and tabulated below.

Table showing concentration of A over time for chemical kinetics analysis.

Determine the rate order and calculate the rate constant. Determine the rate when [A] = 0.04 M.

Accepted Answer

Reaction order: zero-order
k = 3.8 × 10^–3 M/s
Rate = 3.8 × 10^–3 M/s

Answer

Reaction order: first-order
k = 7.3 × 10^–4 s^–1
Rate = 1.5 × 10^–4 M/s

Answer

Reaction order: second-order
k = 9.2 × 10^–2 M^–1 s^–1
Rate = 4.5 × 10^–2 M/s

For the reaction A → B, the concentration of A is observed over time and tabulated below.Determine the rate order and calculate the rate constant. Determine the rate when [A] = 0.04 M.
