A metal oxide reacts chemically with water to form a base in the reaction shown below. If the temperature of the metal oxide and

Alla [95]

increase the rate of chemical change.

Explanation:

The reaction of the metal oxide with water to form a base in the presence of a spike in temperature will lead to an increase in the rate of chemical change.

Temperature change has considerable effect on reaction rates.

Temperature is directly proportional to the average kinetic energy of reacting particles.
Reaction rates varies directly with a spike in temperature.
It has been known that for every 10°C rise in temperature, above the room temperature, reaction rates become double or tripled.
Temperature increases the kinetic energy of each of the reacting particles.
Many of the reacting particles also acquires an energy greater than or equal to the activation energy of the reaction.
The frequency of ordinary collisions and effective collisions per unit time increases.
