The generic reaction occurs in a closed container: $$\mathrm{A}(g)+2 \mathrm{B}(g) \longrightarrow 2 \mathrm{C}(g)$$ A reaction mixture initially contains 1.5 $\mathrm{L}$ of $\mathrm{A}$ and 2.0 $\mathrm{L}$ of B. Assuming that the volume and temperature of the reaction mixture remain constant, what is the percent change in pressure if the reaction goes to completion?

Key Concepts

Reaction Stoichiometry

Reaction stoichiometry involves using the balanced chemical equation to determine the quantitative relationships between reactants and products. It enables the calculation of the amounts of substances consumed and produced during a reaction, providing insight into how the mole ratios impact the overall reaction process.

Limiting Reactant

The concept of the limiting reactant is crucial in predicting the extent of a chemical reaction. It is defined as the reactant that is completely consumed first, thereby limiting the amount of product formation. Understanding which reactant is limiting helps determine how the total number of gas moles changes as the reaction progresses, directly affecting the pressure in a closed system.

Ideal Gas Law

The Ideal Gas Law (PV = nRT) is a fundamental relation in physical chemistry that connects pressure, volume, temperature, and the number of moles of a gas. When the temperature and volume are held constant, any change in the number of moles of gas directly affects the pressure. This principle is essential for understanding how chemical reactions that alter the number of gaseous molecules influence the system’s pressure.
