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.

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
