Chapter 7, Problem 7.50AP

Interpretation Introduction

Interpretation:

The reason for why catalyst does not change the reactants and products at equilibrium has to be explained briefly.

Concept Introduction:

• Reactant: In a chemical reaction the species that present left is denoted as reactant which undergoes chemical change and result to given new species called product.
• Product: In a chemical reaction the species that present in right side is denoted as product that results from the reactant.
• Backward Reaction: This type of reaction process involved a reversible, if the products can be converted into a back to reactants.
• Forward Reaction: This type of reaction has involved irreversible, if obtained product cannot be converted back in to respective reactants under the same conditions. 
• Chemical equilibrium: The term applied to reversible chemical reactions. It is the point at which the rate of the forward reaction is equal to the rate of the reverse reaction. The equilibrium is achieved when the concentrations of reactants and products become constant.
• Catalyst: The catalyst is a chemical substance that increases the rate of the reaction without participating in the reaction by reducing the activation energy of the reaction.
