In a study of rate of reaction

3X + 2Y + Z → 2XY + XZ

Solutions containing different initial concentrations of X, Y and Z were allowed to react. The time taken for the concentration of XY and XZ to reach a certain level was measured. The results are shown in the picture.

The rate law for the reaction above is:

Compound A (represented by circles) converts to compound B (represented by squares) in a first-order process, as represented by the scenes:

The half-life, t_1/2, of the reaction is:

For the reaction:

X₂ + Y + Z → XY + XZ

It is found that halving the concentration of X2 reduces the reaction rate by a factor of 0.5, tripling the concentration of Y, the reaction rate increases by a factor of 9 and doubling the concentration of Z, has no effect on the rate. The rate law for this reaction is:

Solutions containing different initial concentrations of X, Y and Z were allowed to react. The time taken for the concentration of XY and XZ to reach a certain level was measured. The results are shown in the picture.

Using the results, the order of reaction with respect to X and Y respectively are:
