What is the rate for the second order reaction A → Products when [A] = 0.661 M? (k = 0.761 M⁻¹s⁻¹)

Answer 1

For a second order equation, rate = k[A]² = 0.761M^-1s^-1 (0.661M)² = 0.332Ms^-1

Answer 2

A second order reaction has the rate equation:

Rate = k [A]².

∴ Rate = 0.761/M-s x 0.661² = 0.332 M/s.
