Aliquid is placed in an evacuated, sealed flask. when will this closed system reach dynamic equilibrium? when all of the liquid has evaporated to form a vapor when liquid and vapor are present but evaporation stops when the rate of evaporation equals the rate of condensation when the volume of liquid equals the volume of vapor

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 :
