3. Discuss why knowledge of the kinetics and equilibrium of a chemical reaction would be of importance to a chemist. Include in your discussion a definition of kinetics and of equilibrium .
One reason for the importance of kinetics is that it provides evidence for the mechanisms of chemical processes. Besides being of intrinsic scientific interest, knowledge of reaction mechanisms is of practical use in deciding what is the most effective way of...

Enter a balanced chemical equation for the reaction of solid rubidium with liquid water. Express your answer as a chemical equation. Identify all of the phases in your answer.
Rubidium is an alkali metal in the same group (Group I) as sodium and as one goes down the group the ionization energy decreases.Hence Rb also reacts with water leading...

Consider the following reaction at equilibrium: 2 NOBr(g) + heat <- -> 2 NO(g) + Br<sub>2</sub>(g) If the reaction mixture is moved to a larger vessel, the equilibrium will
By increasing the volume of vessel, the pressure decreases.Therefore the system will occupy a bigger volume than it did before the decrease in pressure.Therefore the equilibrium will shift to the...

What are spontaneous reactions? Give an example of a spontaneous reaction and state the criterion of spontaneity of reaction?
A process that occurs spontaneously and minimizes the potential energy of the system is called spontaneous. Example: CH4 +2O2 = CO2 + 2H2OCriterion: ∆G≤0
