the slowest step in a reaction mechanism requires the collision represented above to occur. Which of the following most likely indicates how the addition of a solid catalyst could increase the rate of the reaction?

D. The catalyst could absorb one of the particles, making a successful (reaction-producing) collision with the other particles more likely.

Explanation:

The way that a solid (heterogenous) catalysts functions is by the reactant getting adsorbed to the surface of the catalyst at active sites. An interaction between the surface of the catalyst and the reactant makes the reactants more reactive, causing the reaction to happen.

the only liquid elements at standard temperature and pressure are bromine (br) and mercury (hg). although, elements caesium (cs), rubidium (rb), francium (fr) and gallium (ga) become liquid at or just above room temperature.
