Given that a chlorine-oxygen bond has an enthalpy of 243 kj/mol , an oxygen-oxygen bond has an enthalpy of 498 kj/mol , and the standard enthalpy of formation of clo2 102.5 kj/mol , calculate the value for the enthalpy of formation per mole of clo(g). what is the value for the enthalpy of formation per mole of clo(g)?

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 :

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
