Which of the following are not at equilibrium? Check all that apply. Check all that apply. The concentrations of reactants and the products are not constant. The rate of the forward reaction does not change. The rates of the forward and reverse reactions are equal.

Statements that doesn't portray equilibrium from the question are;

The concentrations of reactants and the products are not constant.

The rates of the forward and reverse reactions are equal.

A chemical equilibrium can be regarded as a state whereby, reactants as well as products that are  present in concentrations doesn't have any tendency to change with time.At equilibrium, the rate of the forward reaction can be different from that of backward reaction.

Therefore, at equilibrium the temperature is constant.

The concentrations of reactants and the products are not constant and the rates of the forward and reverse reactions are equal. and these reactions are not at equilibrium.

Explanation:

The conditions to attain equilibrium is that,

Conversion of reactant to product and vice versa occurs at the same rate.The system is a closed system.The temperature remains constant.Concentration of every substance remains constant.Rate of forward and reverse reactions will be different.

So the answer is The concentrations of reactants and the products are not constant and the rates of the forward and reverse reactions are equal.

Answer is to avoid experimental error

Density and pressure
