Question

Which of the following graphs are correct for a zero order reaction?

• A.
• B.
• C.
• D.

Answer 1

Answer: (A), (D)

For a zero order reaction,

On comparing with equation of straight line $y=[R]$ concentration
$x=t$ time
Slope $(m)=-k$ rate constant
Intercept $(c)=[R{]}_0$ initial concentration
On rearranging Eq. (i)
$\frac{[R]-[R{]}_0}{t}=-k$
$\frac{[R]-[R{]}_0}{t}=-k{t}^0$
Rate $\propto t^0$
