Explanation:
1. Activation Energy:
A catalyst works by providing an alternative reaction pathway with a lower activation energy. The activation energy is the energy required to initiate a chemical reaction. By lowering the activation energy, the catalyst allows the reaction to proceed more easily and at a faster rate.
2. Low Energy Pathway:
Catalysts provide a new reaction pathway that has a lower energy barrier than the original pathway. This allows for more reactant molecules to overcome the energy barrier and convert into products. In other words, the catalyst facilitates the reaction by providing an alternative route that requires less energy.
3. Rate of Reaction:
By lowering the energy barrier for the reaction, the catalyst increases the rate at which reactants are converted into products. This is because more molecules have sufficient energy to react, leading to a higher reaction rate.
4. Equilibrium Composition:
A catalyst does not affect the equilibrium composition of a reaction mixture. It only speeds up the rate at which equilibrium is reached by facilitating both the forward and reverse reactions equally.
In conclusion, a catalyst increases the rate of a chemical reaction by providing a new low energy pathway for the reaction to proceed. This results in a faster conversion of reactants to products without affecting the equilibrium composition of the reaction mixture.
