At 25 °C, the initial rate of reaction is 3.1 × 10−3 mol dm−3 s−1 when the initial concentration of C is 0.48 mol dm−3 and the initial concentration of D is 0.23 mol dm−3 . Calculate a value for the rate constant at this T when rate = k [C][D].

The rate equation is given. So the first step is rearranging it to make the rate constant k the subject of the equation, by dividing both sides by [C][D]. k = (rate/[C][D]) now plug in the values given in...
