. 2 The reactants are completely consumed in the reaction. The kinetic energy of the system is zero. The concentrations of the products and reactants are constant.

No changes will be apparent as the forward in reverse reactions continue. Matter cannot be created or destroyed in a chemical reaction B. The rate of the forward reaction is greater than the rate of the reverse reaction.

1 the products are completely consumed in the reaction. Mar 15 2022. 1 The concentrations of the products and reactants are equal.

For any chemical reaction to be at equilibrium the rate of formation of the products must equal the rate of formation of the reactants such that at equilibrium their mass remains constant. 1 The products are completely consumed in the reaction. Use the dissociation reaction to answer the question.

3 The concentrations of the products and reactants are equal. 3 the same and the reaction has stopped. Reactants will convert to products The Gibbs free energy has reached a minimum The forward reaction rate is not equal to the reverse reaction rate O The concentration of product is equal to the concentration of reactant.

3 by adding water h2O. Which statement describes a chemical reaction at equilibrium. A small value K 1 indicates that the equilibrium reaction lies to the left in favor of reactants.

The appearance Will continue to change as the forward reaction continues at a slow balanced rate. Reactants and products are consumed and formed at the same rate. 4 The rate of the forward reaction is greater than the rate of the reverse reaction.

Which statement best describes the law of conservation of mass. The concentrations of the products and reactants are equal. Aug 2006-19 A chemical reaction is at equilibrium.

Which of the following statement describes a reversible chemical reaction that has reached equilibrium. Reactants in a chemical reaction rearrange to form a new substance or substances C. The principle relating the balanced chemical equation of a reversible reaction to its mass action expression or equilibrium constant expression Mass Action Expression.

3 The rate of the forward reaction is less than the rate of the reverse reaction. Both forward and reverse reactions have stopped. 2 The concentrations of the products and reactants are constant.

Molecules of reactants and products collide with the same frequency. 1 The rate of the forward reaction equals the rate of the reverse reaction. 2 faster and more product is produced.

The system consumes energy at a steady rate. The amounts of reactants and products do not change. A solution at equilibrium is yellow-orange.

Which statement describes a chemical reaction at equilibrium. FeSCN2 aq Fe3 aq SCN- aq In the reaction FeSCN2 ions are red Fe3 ions are pale yellow and SCN- ions are colorless. Reactants and products are consumed and formed at the same rate.

Chemistry questions and answers. The concentrations of reactants and products are equimolar. The system can do no work.

Which statement is always true for a chemical reaction that has reached equilibrium. Compared to the rate of the forward reaction the rate of the reverse reaction is. Le Chateliers Principle If a system is at equilibrium and any change is made to concentration pressure or temperature the reaction will shift to undo the effect of the stress and a new equilibrium is re-established.

4 the same and the reaction continues in both directions. Law of Mass Action. 1 faster and more reactant is produced.

Reactant molecules and product molecules have the same velocity. Molecules of reactants and products collide with the same frequency. The system releases energy at a steady rate.

Reactant molecules and product molecules have the same velocity. The concentration of SCN- ions is increased by a moderate amount. 4 The additional bromine ions cause the equilibrium to shift to the reactants.
