1. The reaction A+B C takes place on a solid catalyst. All the components are gases under the reaction conditions. A molecule of compound B adsorbs on a single catalyst site, and reacts with a molecule of compound A that is in the gas phase, forming a molecule of C that is adsorbed on the same catalyst site. Based on the Langmuir-Hinshelwood form of rate laws, write the rate law for the reaction in terms of partial pressures. [6] a. -CA - b. On the axes below, sketch the expected trend in rate as PB increases, if all other conditions are held constant. [2] -TA PB
