Thermodynamics, Kinetics and Equilibrium

Front

What is the main requirement for a reaction to occur between colliding particles?

Back

The colliding particles must have proper orientation and sufficient energy.

Front

What happens to the entropy of a system when NaCl dissolves in water?

Back

The entropy of the system increases.

Front

How does an exothermic reaction feel to the touch?

Back

An exothermic reaction feels warm.

Front

Which state of matter has the highest entropy?

Back

A hot gas has the highest entropy.

Front

What does Le Chatelier's Principle state?

Back

A change in pressure, temperature, or concentration of a reactant applied to a system in equilibrium will shift to counteract the effect of the change.

Front

Define thermodynamics.

Back

Thermodynamics is the study of energy, heat, and work, and how they relate to physical and chemical processes.

Front

What is kinetic energy in the context of chemical reactions?

Back

Kinetic energy is the energy possessed by particles due to their motion, which affects the rate of reactions.

Front

What is the difference between endothermic and exothermic reactions?

Back

Endothermic reactions absorb heat from the surroundings, while exothermic reactions release heat.

Front

What is activation energy?

Back

Activation energy is the minimum energy required for a chemical reaction to occur.

Front

Explain the concept of equilibrium in a chemical reaction.

Back

Equilibrium is the state in which the rates of the forward and reverse reactions are equal, resulting in constant concentrations of reactants and products.
