What is the half-life (in seconds) of a zero-order reaction which has an initial reactant concentration of 0.834 m with a k value of 5.42 * 10-2 m/s?

The half life (in seconds) of a zero order reaction which has an initial reactant concentration of 0.834 m and k value of 5.42 x10^-2 m/s is 7.694 sec

calculation

t 1/2 = [Ao] / 2k

wher Ao = initial concentration and k = constant

t 1/2 = 0.834 m / (2x5.42 x10^-2 m/s) = 7.694 sec
