Calculate the initial rate for the formation of c at 25 ∘c, if [a]=0.50m and [b]=0.075m

The initial rate for the formation of C at 25°C, if [A]=0.50M and [B]=0.075M is 0.022 M/s

Calculate the initial rate for the formation of C at 25°C, if [A]=0.50M and [B]=0.075M. Express your answer to two significant figures and include the appropriate units. Consider the reaction

A+2B → C

whose rate at 25°C was measured using three different sets of initial concentrations as listed in the following table:

Trial                    [A]                    [B]                    Rate

                         (M)                   (M)                    (M/s)

1                       0.20                 0.030                1.4 x 10 - 3  

2                       0.20                 0.060                2.9 x 10      - 3

3                       0.40                 0.030                5.8 x 10       - 3

We will take a look on 1st and 3rd data.
