Question

$A\to B$
The reaction rate for the above reaction is:

• A. $-\frac{d\left[A\right]}{dt}$
• B. $-\frac{d\left[B\right]}{dt}$
• C. $-\frac{dt}{d\left[A\right]}$
• D. $-\frac{d\left[AB\right]}{dt}$

Answer 1

The correct option is A $-\frac{d\left[A\right]}{dt}$

$A⟶B$

Rate of reaction = Either rate of disappearance of $A$ or rate of appearance of $B$

i.e; Rate=$\frac{-d\left[A\right]}{dt}=\frac{d\left[B\right]}{dt}$
