Question

Assertion: For the reaction
$CHCl_{3} + Cl_{2} \to CCl_{4} + HCl$
Rate $= k[CHCl_{3}] [Cl_{2}]^{1/2}$
Reason: Rate of reaction is always equal to the sum of the stoichiometric coefficients of the reacting species in a balanced chemical equation.

• A. If both assertion and reason are true and reason is the correct explanation of assertion.
• B. If both assertion and reason are true but reason is not the correct explanation of assertion.
• C. If assertion is true but reason is false.
• D. If both assertion and reason are false.

Answer 1

Answer: (C)

Rate of reaction depends upon the experimental conditions such as concentration of reactants, temperature and catalyst. It may or may not be equal to the stoichiometric coefficients of the reacting species in a balanced chemical equation.
