Searches related to Two identical beakers with exactly the same amount of warm water were prepared. Th e first beaker was allowed to cool by sitting in a classroom with an air temperature of 233 degrees C. The second beaker was placed in a large bucket of ice water at 0 degrees C. The temperature of each was measured every minute for 45 minutes. Which beaker of water starts off at higher temperature?

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 :
