The speed of a chemical reaction

a. is constant no matter what the temperature is.

b. is independent of the amount of contact surface of a solid involved.

c. between gases should in all cases be extremely rapid because the average kinetic energy of the

molecules is great.

d. between ions in aqueous solution is extremely rapid because there are no bonds that need to be

broken.
