The plot of concentration of the reactant vs time for a reaction is a straight line with a negative slope. This reaction follows

A

zero order rate equation

B

first order rate equation

C

second order rate equation

D

third order rate equation

Text Solution

Verified by Experts

The correct Answer is:
B
for first order reaction we know that
`log [A]=-(kt)/(2.303)+log[A]_(0)`
On comparing it with the equataionn of straight line
`i.e., y=mx+c`
Plot of log [A] versus time `to` straight line
slope `=(-k)/(2.303)("negative")`
