Question

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?

Answer 1

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

Answer 2

I should be using the zeroth half-life order right? t1/2=0.5[A]0(k)

Answer 3

yup it's divided by k though, not multiplied.

Answer 4

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

Answer 5

yep

Answer 6

My answer was 2.87

Answer 7

cool

Answer 8

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

Answer 9

we'll that should be the correct answer. are the answers given in order of hours?

Answer 10

Yeah the answers are given in hrs

Answer 11

weird, because that IS the answer.

Answer 12

Ok. Thanks

Answer 13

no problem
