** will give brainliest ** which of the following statements explains how temperature affects the rate of a reaction? a. when temperature decreases, collision of particles increases. b. when temperature decreases, kinetic energy increases. c. when temperature increases, particles move slower. d. when temperature increases, particles move faster.

The answer would be D. when temperature increases, particles move faster.

D. When temperature increases, particles move faster.

Explanation:

Rate of reaction is directly proportional to the temperature of a reaction.

Activation energy is the extra energy that must be supplied to reactants in order to cross the energy barrier and thus convert to products.

Increasing the temperature means more particles can cross the energy barrier, because the kinetic energy of the particles increases , thus particles can move faster. More of them can undergo effective collisions. This leads to increase in the rate of the reaction.

stupid i wont let you get a chance

explanation:

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
