which will increase the rate of a chemical reaction?\nadding a catalyst\ndecreasing the pressure\ndecreasing the temperature\nremoving a catalyst
Answer
Brief Explanations:
A catalyst lowers the activation - energy of a chemical reaction, allowing more reactant molecules to have enough energy to react and thus increasing the reaction rate. Decreasing pressure and temperature generally slow down reactions, and removing a catalyst won't increase the rate.
Answer:
adding a catalyst
