7B.9

Postby Maggie Doan 1I » Wed Mar 13, 2019 2:15 pm

For the first order reaction A 3B + C, When [A]0 = .015 mol/l, the concentration of B increases to .018 mol/ L in 3.0 min.

a) What is the rate of constant for the reaction expressed as the rate of loss of A?

I got the answer 1.7 minutes but the answer is .17 minutes. I was wondering how they got the answer.

If you use the equation you should get the right answer. I recommend rechecking your math as you probably put a decimal point in the wrong place.

the mistake is more likely in your unit conversions, I would just double check those.
