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 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?

aaronq · Answer

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

anonymous · Answer

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

aaronq · Answer

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

anonymous · Answer

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

aaronq · Answer

yep

anonymous · Answer

My answer was 2.87

aaronq · Answer

cool

anonymous · Answer

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

aaronq · Answer

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

anonymous · Answer

Yeah the answers are given in hrs

aaronq · Answer

weird, because that IS the answer.

anonymous · Answer

Ok. Thanks

aaronq · Answer

no problem
