Identify the relationship between the given reaction and the new reaction. The new reaction is essentially the given reaction multiplied by 2.
Recall that when a reaction is multiplied by a factor, the equilibrium constant (Kp) for the new reaction is the original Kp raised to the power of that factor.
In this case, the factor by which the original reaction is multiplied is 2.
Calculate the new Kp by raising the original Kp to the power of 2. This means you will calculate (7.2 * 10^7)^2.
The result from the calculation in step 4 will give you the Kp for the new reaction.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Equilibrium Constant (Kp)

The equilibrium constant (Kp) is a numerical value that expresses the ratio of the concentrations of products to reactants at equilibrium for a given reaction, with each concentration raised to the power of its coefficient in the balanced equation. It is specific to a particular temperature and provides insight into the extent of a reaction. A larger Kp indicates a greater concentration of products at equilibrium.

Equilibrium Constant Expressions

Reaction Stoichiometry

Reaction stoichiometry refers to the quantitative relationship between the reactants and products in a chemical reaction, as represented by the coefficients in a balanced equation. When deriving Kp for a different reaction, it is essential to adjust the coefficients accordingly, as this affects the powers to which the concentrations are raised in the Kp expression. Understanding stoichiometry is crucial for manipulating equilibrium constants.

Stoichiometry Concept

Temperature Dependence of Kp

The value of Kp is temperature-dependent, meaning that changes in temperature can alter the equilibrium position of a reaction. For a given reaction, Kp is only valid at a specific temperature, and any change in temperature will require recalculating Kp. This concept is vital when comparing Kp values for reactions occurring at the same temperature, as in the provided question.
