BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Changing the Temperature It is also true that cooling a reaction will slow it down. At lower temperatures, the particles are moving more slowly, and fewer particles have an energy greater than the activation energy, and so cannot collide with enough energy to cause bonds to break.

Detailed explanation-2: -When you lower the temperature, the molecules are slower and collide less. That temperature drop lowers the rate of the reaction.

Detailed explanation-3: -Usually reactions speed up with increasing temperature. Physical state of reactants. Powders react faster than blocks-greater surface area and since the reaction occurs at the surface we get a faster rate.

Detailed explanation-4: -This statement is False: Increasing the temperature of a reaction lowers the activation energy of the reaction. Generally, the factor that lowers the activation energy of a reaction is the use of a catalyst.
