What is meant by the Terrestrial and Hydrologic parts of Earth?

Not sure what you exactly mean, but I think what you are talking about are the spheres of earth (Lithosphere, Hydrosphere, Atmosphere, and Biosphere.)

Lithosphere (Terrestrial) is the land on earth. Hydrosphere (Hydrologic) is the water on earth.

I'm not sure if this is 100% correct but I'm guessing this is what you are referring to. It could be different across different science classes.

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 :
