4.21 The following data were obtained during the first order thermal decomposition of at a constant volume.
Calculate the rate of the reaction when total pressure is 0.65 atm.
The thermal decomposition of is shown here;
After t time, the total pressure =
for first order reaction,
now putting the values of pressures, when t = 100s
= 0.65 - 0.5
= 0.15 atm
= 0.5 - 0.15
= 0.35 atm
Thus, rate of reaction, when the total pressure is 0.65 atm
rate = k()
