Problem

rate = k[A][B]^2

. In Experiment 1,

[A] = 0.20\,\text{M}

and

[B] = 0.10\,\text{M}

. In Experiment 2,

[A] = 0.40\,\text{M}

and

[B] = 0.30\,\text{M}

. The temperature is the same in both experiments, so

k

is unchanged. By what factor does the initial rate in Experiment 2 differ from that in Experiment 1? (a)
