Question

Equilibrium is reached in chemical reactions when: A) The rates of the forward and reverse reactions become equal. B) The concentrations of reactants and products become equal. C) The temperature shows a sharp rise. D) All chemical reactions stop.

Answer 1

Answer:

A

Explanation:

1. Chemical equilibrium : is the chemical reversible reaction in which the rate of the forward reaction ( formation of product from reactants) is equals to the rate of the reverse reaction( converting products into reactants). When a reaction is in equilibrium,  then the concentration of the reactants and products are constant.

2. Examples of chemical equilibrium : bottle of fizzy cool drink, and there are also  many other examples of chemical equilibrium.

Answer 2

Answer:

Correct option: A

Explanation:

Equilibrium means the state of reaction which there is no net changes occur it means the rate of forward reaction and rate of backward reaction become same and also it does not mean that the concentration of both side i.e. reactant and product become equal. after gaining equlibrium position the concentration of reactant and product remain same and also chemical reaction does not stop and it continues.
