The experimental data for the decomposition of
`N_(2) O_(5) , [2N_(2) O_(5) to 4NO_(2) + O_(2)]`
in gas phase of 318 K are given below:

Calculate the rate constant.

Text Solution

Verified by Experts

For first order reaction, the slope of the line
`= - (k)/( 2.303)" "…(i)`
`therefore` Slope `= (-2.46 - (-1.79) )/( 3200-0) = (-0.67)/( 3200)" "...(ii)`
From Eqs. (i) and (ii), we get
`- (k)/( 2.303) = (-0.67)/( 3200)`
or `k= (0.67 xx 2.303)/( 3200)` or `k = 4.82 xx 10^(-4)" s"^(-1)`
