Question

Hypothesis: Explain the relationship between forward and reverse reactions at equilibrium and predict how changing the amount of a reactant or product (creating a stress) will affect that relationship.

Answer 1

Step-by-step explanation:

forward reaction

a reaction in which reactent react to form product is known as forward reaction

reverse reaction

a reaction in which product react to form reactent is known as reverse reaction

At equilibrium stage

In a chemical equilibrium, the forward and reverse reactions occur at equal rates, and the concentrations of products and reactants remain constant. A catalyst speeds up the rate of a chemical reaction, but has no effect upon the equilibrium position for that reaction.

changing amount of reactent and product

lechatlier principle

" if you impose any change in concentration ( reactant or product) , temperature or pressure on chemical system, the system response in that way that opposes the change "
