for a reaction 2A+B\rightarrow3 C

What is the rate of the reaction with respect to A?

Option: 1

-\frac{d[A]}{dt}


Option: 2

-\frac{d[A]}{dt}+\frac{d[C]}{dt}-\frac{d[B]}{dt}


Option: 3

-\frac{d[B]}{dt}


Option: 4

-\frac{1}{2}\frac{d[A]}{dt}

Rate of reaction -

The rate of the reaction during the courses of a reaction in any instant of time is the change in concentration of reacting species. Rate is a positive quantity.

 

 \mathrm{Rate\: of\: reaction \: w.r.t.\: A=-\frac{1}{2}\frac{\mathrm{d} \left [ A \right ]}{\mathrm{d} t}}

\mathrm{Rate\: of\: reaction \: w.r.t.\: B=-\frac{\mathrm{d} \left [ B \right ]}{\mathrm{d} t}}

\mathrm{Rate\: of\: reaction \: w.r.t.\: A=\frac{1}{3}\frac{\mathrm{d} \left [ C \right ]}{\mathrm{d} t}}

Option 4 is correct.
