Half life with rate order

Question

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 0.725?

Answer 1

The half life for a zero order reaction is given by t_1/2 = [A]_o / 2k

t_1/2 = 276 s

[A]_o = 0.725 M (not units were given, but it is safe to assume they are moles/L or M)

k = ?

Simply plug in the values and solve for k

276 s = 0.725 M / 2k

2k = 0.725 M / 276 s

2k = 0.002627 M/s

k = 0.00131 M/s
