At a certain temperature the rate of this reaction is first order in with a rate constant of Suppose a vessel contains at a concentration of . Calculate how long it takes for the concentration of to decrease to of its initial value. You may assume no other reaction is important. Round your answer to significant digits.

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
