Calculate the initial rate for the formation of c at 25 ∘c, if [a]=0.50m and [b]=0.075m
Alenkinab [10]
Rate = k * [A]^2 * [B]^1 

<span>Use the data from any trial to calculate k. </span>

<span>k = (rate)/([A]^2 * [B]^1) </span>

<span>E.g., for Trial 1, we have </span>

<span>rate = 3.0×10−3 M/s </span>
<span>[A] = 0.50 M </span>
<span>[B] = 0.010 M </span>

<span>Plug those numbers in and crank out the answer. </span>

<span>Now with the calculated value of k, calculate the initial rate for [A] = 0.50 M and [B] = 0.075 M </span>

<span>rate = k * [A]^2 * [B]^1 </span>

<span>k = calculated value </span>
<span>[A] = 0.50 M </span>
<span>[B] = 0.075 M</span>
