The tabulated data were collected for this reaction at a certain temperature: X2Y → 2 X + Y c. What is the concentration of X after 10.0 hours?

검증된 단계별 안내
1
Determine the rate law for the reaction. This involves understanding how the concentration of reactants affects the rate of the reaction.
Use the integrated rate law that corresponds to the order of the reaction. For example, if it's a first-order reaction, use the first-order integrated rate law: \( [A] = [A]_0 e^{-kt} \).
Identify the initial concentration of X, \([X]_0\), from the data provided.
Calculate the rate constant \(k\) using the data provided and the appropriate rate law.
Substitute the values of \([X]_0\), \(k\), and \(t = 10.0\) hours into the integrated rate law to find the concentration of X after 10.0 hours.

주요 개념

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

Chemical Reaction Stoichiometry

Stoichiometry involves the calculation of reactants and products in chemical reactions based on balanced equations. In the given reaction, X<sub>2</sub>Y decomposes into 2 moles of X and 1 mole of Y, indicating the molar relationships between the substances. Understanding these ratios is essential for determining the concentration of products formed over time.

Stoichiometry Concept

Concentration and Molarity

Concentration refers to the amount of a substance in a given volume of solution, commonly expressed in molarity (moles per liter). To find the concentration of X after a specified time, one must consider the initial concentration of reactants and how they change as the reaction proceeds. This concept is crucial for quantifying the amount of X produced after 10.0 hours.

Reaction Kinetics

Reaction kinetics studies the rates of chemical reactions and the factors affecting them. The time factor in the question (10.0 hours) is significant, as it influences how much of the reactants have converted into products. Understanding the kinetics of the reaction helps predict the concentration of X at a specific time point.
