Question
The order of a reaction, with respect to one of the reacting component $$Y,$$ is zero. It implies that :
A.
the reaction is going on at a constant rate
B.
the rate of reaction does not vary with temperature
C.
the reaction rate is independent of the concentration of $$Y$$
D.
the rate of formation of the activated complex is zero
Answer :
the reaction rate is independent of the concentration of $$Y$$
Solution :
Let us consider a reaction,
$$\eqalign{
& xX + yY \to aA + bB \cr
& rate = {\left[ X \right]^x}{\left[ Y \right]^y} \cr} $$
It is given that order of reaction $$w.r.t$$ . component $$Y$$ is zero.
Hence, rate $$ = {\left[ X \right]^x}$$
i.e., rate becomes independent of the concentration of $$Y.$$
