The absolute temperature of a gas is increased four times while maintaining a constant volume. What happer pressure of the gas?
It decreases by a factor of four.
It increases by a factor of four.
O It decreases by a factor of eight.
O It increases by a factor of eight.

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 :

the answer is c
