Step-by-Step Solution
Solution 1
The substance which is used to increase the rate of a chemical reaction is defined as catalyst.
Catalyst does not add any energy to the substance, does not increase any energy to the overall reaction, and speeding up the overall reaction process. It is used to increase the rate of the chemical reaction by reducing required energy of the reaction.
Hence, the options A, B, and D are wrong.
Catalyst is used to reduce the required energy. Hence, it is a substance that finding an alternative method to reduce the required energy for the reaction.
Hence, the correct option is
