The rate equation governing the industrial synthesis of ammonia is___________________?
Show answer Hide answer
Answer: D. Kc=4x2v2/(a-x)(b-3x)3
Explanation
The correct expression incorporates stoichiometric coefficients as powers according to the law of mass action. Equilibrium constants for gas phase reactions use concentration or pressure terms raised to their balanced coefficients. The Haber process equation requires careful placement of reactant and product terms to reflect stoichiometry accurately. The industrial synthesis of ammonia combines nitrogen gas and hydrogen gas over an iron based catalyst. Chemical equilibrium expressions relate the concentrations of reactants and products at a constant reaction temperature. Stoichiometry dictates that one mole of nitrogen reacts with three moles of ammonia precursors.
Ammonia production is vital for manufacturing agricultural fertilizers that support global food crop yields. Chemical engineers use these equilibrium equations to maximize product yield under high pressure conditions. Optimizing industrial chemical processes reduces energy consumption and minimizes costly reactant waste. Other mathematical choices fail to correctly position the stoichiometric coefficients as exponential power terms. Incorrect reactant ratios in alternative expressions violate the fundamental balanced chemical equation rules. Incorrectly formatted equilibrium expressions cannot accurately predict product yields for industrial reactor designs.
