Chemistry Question on Rate of a Chemical Reaction
The value of rate constant of a pseudo first order reaction
A
Depends only on temperature
B
Depends on the concentration of reactants present in small amounts
C
Depends on the concentration of reactants present in excess
D
Is independent of the concentration of reactants
Answer
Depends on the concentration of reactants present in excess
Explanation
Solution
The value of the rate constant of pseudo-first-order reaction depends on the concentration of reactants present in excess amount. A pseudo-first-order reaction can be defined as a second-order or bimolecular reaction that is made to behave like a first-order reaction. This reaction occurs when one reacting material is present in great excess or is maintained at a constant concentration compared with the other substance.
