Verified step by step guidance

Identify the balanced chemical equation: 2 NOCl(g) → 2 NO(g) + Cl2(g). This equation shows the stoichiometric relationship between the reactants and products.

Understand the relationship between the rates of reaction for different species. According to the stoichiometry of the reaction, 2 moles of NOCl produce 1 mole of Cl2.

Use the stoichiometric coefficients to relate the rate of loss of NOCl to the rate of formation of Cl2. The rate of loss of NOCl is twice the rate of formation of Cl2 because 2 moles of NOCl are consumed for every 1 mole of Cl2 produced.

Express the rate of loss of NOCl in terms of the rate of formation of Cl2 using the stoichiometric coefficients: Rate of loss of NOCl = 2 × Rate of formation of Cl2.

Substitute the given rate of Cl2 formation (4.84e-2 M/s) into the expression: Rate of loss of NOCl = 2 × 4.84e-2 M/s. This will give you the rate of loss of NOCl.
