Select all of the true statements regarding chemical equilibrium. Select one or more: The concentrations of reactants and products are equal. Reactants are being converted to products and vice versa. The concentrations of reactants and products remain constant. The rates of the forward and reverse reactions are equal.

The statements:

The concentrations of reactants and products remain constant. The rates of the forward and reverse reactions are equal.

are TRUE

Explanation:

Chemical equilibrium is the state of a reversible reaction where the rate of the forward reaction equals the rate of the reverse reaction. While a reaction is in equilibrium the concentration of the reactants and products are constant. ... There are many examples of chemical equilibrium all around you.

The equilibrium constant of a chemical reaction is the value of the reaction quotient when the reaction has reached equilibrium. An equilibrium constant value is independent of the concentrations of the reactant and product species in a mixture but depends on temperature and on ionic strength.

Temperature increase favours the endothermic reaction.
