The reaction, 2 NO(g) + O2(g) → 2 NO2(g), was found to be first order in each of the two reac­tants and second order overall. The rate law is therefore

Explanation:

Hello,

In this case, rate laws allows us to compute how fast a chemical reaction is carried out by means of the change in the concentration of the species affecting the rate. In such a way, since the statement says that the reaction was found to be first order to both nitrogen monoxide and oxygen, it means that their concentrations are powered to first power by separated. It also implies that the overall order is second-order since the specific orders are added (powers properties). Therefore, the rate law is:

Whereas k is the rate constant and we find the concentration of the reactants to the first power each one.

Best regards.

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.
