Q.
Which of the following curve represent zero order reaction of $A \to$ products?
Chemical Kinetics
Solution:
For zero-order reaction
$\frac{-d\left[A\right]}{dt}=k$
or $\left[A\right]_{0}-\left[A\right]=kt$
or $\left[A\right]=\left[A\right]_{0}-kt$
It means concentration of A linearly decreases with t.
