The following data were obtained during the first order thermal decomposition of at a constant volume.
Experiment Time/s Total pressure/atm
1 0 0.5
2 100 0.6
Calculate the rate of the reaction when total pressure is 0.65 atm.
(A). If the reaction is assumed to proceed to completion, the final pressure will be doubled the initial pressure. Then for a first order reaction, one can write.
For total pressure of 0.65 atm,
Rate the reaction
From the reaction stoichiometry,
So, Rate of reaction
