Question

For the reaction $2A+3B\to 4C$ the rate of reaction may be represented as

• A. $r=-2\frac{d\left[A\right]}{dt}=-3\frac{d\left[B\right]}{dt}=4\frac{d\left[C\right]}{dt}$
• B. $r=-6\frac{d\left[A\right]}{dt}=-4\frac{d\left[B\right]}{dt}=3\frac{d\left[C\right]}{dt}$
• C. $r=-\frac{1}{2}\frac{d\left[A\right]}{dt}=\frac{1}{3}\frac{d\left[B\right]}{dt}=\frac{1}{4}\frac{d\left[C\right]}{dt}$
• D. $r=-\frac{1}{2}\frac{d\left[A\right]}{dt}=-\frac{1}{3}\frac{d\left[B\right]}{dt}=\frac{1}{4}\frac{d\left[C\right]}{dt}$

Answer 1

Answer: (D)

For the reaction $2A+3B\to 4C$ the rate of reaction is represented as
$-\frac{1}{2}\frac{d\left[A\right]}{dt}=-\frac{1}{3}\frac{d\left[B\right]}{dt}=\frac{1}{4}\frac{d\left[C\right]}{dt}$
