When a reaction is at equilibrium,

the forward and reverse reactions occur at the same rate

all reaction stops

no more reactants are converted to products

the reaction is no longer reversible

the forward and reverse reactions occur at the same rate

Explanation:

A reaction is in chemical equilibrium when the rate of the forward reaction equals the rate of the reverse reaction.

In equilibrium reaction the concentration of the reactants and products is constant. A reaction is in chemical equilibrium when the rate of the forward reaction equals the rate of the reverse reaction. The chemical equation will be shown as,

α A + β B ⇌ σ S + τ T
