Industrially, hydrogen gas can be prepared by reacting propane gas $\left(\mathrm{C}_{3} \mathrm{H}_{8}\right)$ with steam at about $400^{\circ} \mathrm{C}$. The products are carbon monoxide (CO) and hydrogen gas $\left(\mathrm{H}_{2}\right) .$ (a) Write a balanced equation for the reaction. (b) How many kilograms of $\mathrm{H}_{2}$ can be obtained from $2.84 \times 10^{3} \mathrm{~kg}$ of propane?

Key Concepts

Stoichiometric Yield Calculation

This involves using the balanced chemical equation along with the molar masses of the substances involved to compute the theoretical amount of product that can be formed from a given quantity of reactant. It is an application of both the mole concept and the stoichiometric ratios derived from the balanced equation.

Industrial Steam Reforming

This is a chemical process used in the industry to produce synthesis gas, typically a mixture of hydrogen and carbon monoxide, by reacting hydrocarbons with steam. Understanding this process involves recognizing the reaction conditions, catalysts, and the transformation of a hydrocarbon feedstock into valuable chemical products such as hydrogen.

Chemical Reaction Stoichiometry

This concept involves writing and balancing chemical equations to ensure the conservation of mass, meaning that the number of atoms of each element is the same on both sides of the reaction. It allows us to establish the proportional relationships between reactants and products, which is essential for quantifying how much of a product is generated from given amounts of reactants.

Molar Mass and Mole Concept

Molar mass is the mass of one mole of a substance and is used to convert between the mass of a substance and the number of moles. This conversion is crucial when applying stoichiometric coefficients in a balanced equation to determine the quantitative relationships among reactants and products.
