Question

In the reaction, $A+B⟶C+D$, the rate $\left(\frac{dx}{dt}\right)$ when plotted against time '$t$' gives a straight line parallel to time axis and at some time ${}^{\prime }{t}^{\prime }$, $\frac{dx}{dt}=k$. The order and rate of reaction will be:

• A. $1,k+1$
• B. $0,k$
• C. $(1+k),1$
• D. $k,k+1$

Answer 1

The correct option is B $0,k$

A straight line parallel to time axis indicate that the rate is constant. This is the case for zero order reaction.

$\frac{dx}{dt}=k$

rate of the reaction=k
