Question
Consider the reaction
A+2B⇌CA+2B⇌C
whose rate at 25 ∘C∘C was measured using three different sets of initial concentrations as listed in the following table:
Trial | [A][A] (MM) |
[B][B] (MM) |
Rate (M/sM/s) |
1 | 0.20 | 0.010 | 4.8×10−4 |
2 | 0.20 | 0.020 | 9.6×10−4 |
3 | 0.40 | 0.010 | 1.9×10−3 |
Calculate the initial rate for the formation of CC at 25 ∘C∘C, if [A]=0.50M[A]=0.50M and [B]=0.075M[B]=0.075M.
Express your answer numerically in molar per second using two significant figures.
