Question

Experiments must be designed to analyze the effect of only one reactant per experiment. In the data table below, only [A] was changed between experiment 1 and 2 Only [B] was changed between experiment 1 and 3. Only these two experiments will be used to determine the rate law, comparing experiments? Comparing experiments 1 and 2. [A] increases by a factor of 2 and the rate increases by a factor of 0.2. In this case the only possible value for the order for reactant A is x = 1, because 2 = 2. Comparing experiments 1 and 3, [B] increases by a factor of 2 and the rate increases by a factor of 4. This case is only possible when the of order reactant B is y = 2, because 2^2 = 4.

Explanation / Answer

Keep B constant we u double A then the total rate is doubling

So rate = k(A)

Similarly if u double B with A constant then rate is increasing 4 times.

So rate = k(B)^2

Total rate equation = k(A)(B)^2
