The half-life for the zero order reaction A → Products is 276 s. What is the value of the rate constant for the reaction if the initial concentration of A is 0.417?

Answer 1

For a zero order reaction, the half life (t_1/2) = [A]_o / k

t_1/2 = 276 s

[A]_o = 0.417 M

Solve for k:

276 s = 0.417 M / k

k = 0.417 M / 276 s

k = 0.00151 M/s = 1.51x10^-3 M/s
