Question

Calculate the initial rate for the formation of $\mathrm{C}$ at 25 Degree C∘C, if [A]$[\mathrm{A}]=0.50M$ and [A] = 0.50M$[\mathrm{B] }=0.075M$.

onsider the reaction

A+2B⇌C$\mathrm{A}+2\mathrm{B}\rightleftharpoons \mathrm{C}$

whose rate at 25 ∘C${}^{\circ }\mathrm{C}$ was measured using three different sets of initial concentrations as listed in the following table:

Trial	[A]$[\mathrm{A}]$ (M$M$)	[B]$[\mathrm{B}]$ (M$M$)	Rate (M/s$M/\mathrm{s}$)
1	0.40	0.050	9.6×10−3
2	0.40	0.100	1.9×10−2
3	0.80	0.050	3.8×10−
