This is the general form:|dw:1441073645037:dw|

Try plugging in what you know from the first trial.

So it'd be R = k[0.03][0.005]^3? But what do I do with that?
JoannaBlackwelder
  • JoannaBlackwelder
You plugged in the concentrations correctly, but the exponents are not the coefficients of the balanced reaction. And plug in the rate given as well.

  • JoannaBlackwelder
Leave the coefficients as a and b for now. I'll help you with the tricky step. :-)

I'm still completely confused.

Ok, the info from the first trial gives us 4.3x10^-4=k(0.03)^a(0.005)^b Do you see how I plugged that in so far?
warpedkitten
  • warpedkitten
Yes.

  • JoannaBlackwelder
Cool. You try for the second trial, then I will show you what to do with them.

1.72x10^-3=k(0.03)^a(0.01)]^b

Sweet, now we take those and divide them.

Does that step make sense?

Great! Can you solve for b from here?
