A) temperature
B) concentration of reactant
C) pressure
D) volume
Correct Answer: C
Solution :
Specific rate of a first order reaction does not depend on pressure. It mainly depends on concentration of reactants, temperature of reactants, nature of reacting substance, presence of catalysts and exposure to radiation. Order of a reaction may be defined as number of molecules of the reactants undergoing a considerable change during the reaction. Order of reaction can be zero or a fractional value. Whereas molecularity is defined as the total number of reactant molecules represented by a balanced chemical equation. It has only positive integer value.
