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.

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

At a particular temperature, two gases, A (represented by circles) and B (represented by squares), react to form products. The following molecular scenes represent starting mixtures for four experiments run at the same volume, labeled 1 through 4, with their initial rates (in mol L⁻¹s⁻¹):

The rate law for the reaction above is:

Consider a termolecular reaction of the type

A + 2B → products.

The units of the rate constant for the reaction is:

At a particular temperature, two gases, A (represented by circles) and B (represented by squares), react to form products. The following molecular scenes represent starting mixtures for four experiments run at the same volume, labeled 1 through 4, with their initial rates (in mol L⁻¹s⁻¹):

The value of the rate constant K is:

By what factor does the rate change in each of the following cases (assuming constant temperature)?

A reaction is second order in reactant B, and [B] is halved.
