Here are just a few everyday demonstrations that temperature changes the rate of chemical reaction:
Cookies bake faster at higher temperatures.
Bread dough rises more quickly in a warm place than in a cool one.
Low body temperatures slow down metabolism. In fact, warm-blooded animals regulate body temperature so that their biochemical reactions run at the correct rate.
Lightsticks produce light via a chemical reaction. Dropping a lightstick into hot water makes it glow more intensely, demonstrating that the reaction runs faster at higher temperature.
Increasing the concentration of reactants also changes reaction rate:
Two antacid tablets will neutralize a given amount of acid faster than one tablet will.
Higher concentrations of acid in rain erode marble faster than lower concentrations.
