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

yes definetly because you are using energy

sry but any answer choices
