Questions and Answers

What is the Law of Mass Action and why is it significant in chemistry?

The Law of Mass Action states that the rate of a chemical reaction is proportional to the product of the concentrations of the reactants raised to their respective stoichiometric coefficients. It is significant because it helps in predicting the behavior of chemical reactions at equilibrium.

Define chemical equilibrium and its importance in chemical reactions.

Chemical equilibrium is the state in which the rate of the forward reaction equals the rate of the reverse reaction, resulting in constant concentrations of reactants and products. It is important because it allows for the prediction of the concentrations of substances in a reaction mixture.

What is the Clausius-Clapeyron equation and its application?

The Clausius-Clapeyron equation relates the change in vapor pressure with temperature for a phase transition, given by the formula $rac{dP}{dT} = rac{L}{T riangle V}$. This equation is applied to determine the enthalpy of phase changes such as vaporization.

Differentiate between order of reaction and molecularity of reaction.

<p>Order of reaction is the sum of the powers of the concentration terms in the rate equation, reflecting the overall reaction dependence on concentration. Molecularity, on the other hand, is the number of molecules participating in a single reaction event, indicating the steps involved in the reaction.</p> Signup and view all the answers

Explain the concept of 'degree of freedom' in terms of phase equilibria.

<p>The degree of freedom in phase equilibria is the number of independent variables that can be changed without affecting the number of phases in a system, given by the formula $F = C - P + 2$, where $F$ is the degrees of freedom, $C$ is the number of components, and $P$ is the number of phases. This concept helps in predicting how a system behaves under varying conditions.</p> Signup and view all the answers

Flashcards

Law of Mass Action

The rate of a chemical reaction is proportional to the product of the concentrations of the reactants, each raised to a power equal to its stoichiometric coefficient in the balanced chemical equation.

Chemical Equilibrium

A state in a reversible reaction where the rates of the forward and reverse reactions are equal, resulting in no net change in the concentrations of reactants and products.

Ideal Gas

A gas that perfectly obeys the ideal gas law; assumes no intermolecular forces and negligible molecular volume.

Real Gas

A gas that does not perfectly follow the ideal gas law; accounts for intermolecular forces and molecular volume.
