Best ResponseYou've already chosen the best response.0So it'd be R = k[0.03][0.005]^3? But what do I do with that?

Best ResponseYou've already chosen the best response.1You plugged in the concentrations correctly, but the exponents are not the coefficients of the balanced reaction. And plug in the rate given as well.

Best ResponseYou've already chosen the best response.1Leave the coefficients as a and b for now. I'll help you with the tricky step. :)

Best ResponseYou've already chosen the best response.1Ok, 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?

Best ResponseYou've already chosen the best response.1Cool. You try for the second trial, then I will show you what to do with them.
