Hello,
Say I have a reaction given by,
X + Y :rarrow: 2Z, k=whatever
and I was asked to determine the rate of production of Z, what effect on the rate does the 2 coefficient have? For example, would the rate be,
rate = k[X][Y], as in if there were no coefficient,
or
rate = (1/2)k[X][Y]
or
rate = 2k[X][Y]
or something entirely different?
Thanks.
Edit: It's a second order reaction.

"rate of production of C" Do you mean C or Z?

Oops, I meant Z. I had it as A, B, and C, but turns out square brackets around B made parts of the post bold, so I changed it to X, Y, and Z. Also, it's a second order reaction.

you can define it however you want, just be aware that k will be different in different definitions. its customary to define the rate of a reaction as the rate of change of the concentration of a species divided by its stochiometric coefficient
