Question

select all that apply which of the following is most likely to decrease the rate of a chemical reaction? decrease temperature increase concentration of reactants increase temperature decrease concentration of reactants

Explanation:

The rate of a chemical reaction is affected by temperature and reactant concentration. Lowering temperature reduces the kinetic energy of reactant molecules, decreasing collision frequency and reaction - rate. Reducing reactant concentration means fewer molecules available to collide and react, thus decreasing the reaction rate. Increasing temperature or reactant concentration has the opposite effect, increasing the reaction rate.

Answer:

Decrease temperature, Decrease concentration of reactants
