Under what conditions would pressure affect the reaction rate? O A. If the reaction occurs in the gas phase
O B. If the reaction is between two liquids
O c. If the reaction takes place between a solid and a liquid
D. If the reaction requires the use of a catalyst

if a reaction occurs in a gas phase, then it the pressure would affect the rate of reaction.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
