The rate law for the reaction 3A yields C is Rate=4.36E-2 L mol-1 hr-1 What is the half life for the reaction if the initial concentration of A is 0.250M?

the rate law indicates that it's a zeroth order reaction, do you know which equations to use?

I should be using the zeroth half-life order right? t1/2=0.5[A]0(k)
aaronq
  • aaronq
yup it's divided by k though, not multiplied.

t1/2 = 0.5(0.250M) / 4.36E-2 L x mol x hr?

But it doesn't match any of my answer that is giving though
