2. If 75cm of a gas is at STP, what volume will the gas occupy if the temperature is raised to 75ºC and the pressure is increased to 945 torr?

sry but any answer choices

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 :

there is none because earth is stationary and flat.

the answer is b. dilution
