Question

When a reaction system is at equilibrium: a. there is no more chemistry happening. b. the amounts of reactants and products are exactly equal. c. the reaction rate in the forward direction is at a maximum. d. the reaction rate in the reverse direction is at a minimum. e. the rates of the reaction in the forward and reverse directions are exactly equal.

Answer 1

Answer: Option (e) is the correct answer.

Step-by-step explanation:

Equilibrium is defined as the state of a chemical reaction in which the rate of forward reaction is equal to the rate of backward reaction.

The state of equilibrium is represented by a double sided arrow as "
`\rightleftharpoons`" in a chemical equation.

For example,
`H_(2)O(l) \rightleftharpoons H^(+)(aq) + OH^(-)`

Therefore, we can conclude that when a reaction system is at equilibrium then the rates of the reaction in the forward and reverse directions are exactly equal.
