If is the enthalpy change and the change in internal energy accompanying a gaseous reaction then
View answer and explanation
Correct option: D
is less than if the number of moles of gaseous products is less than the number of moles of gaseous reactants.
The correct answer is D ( is less than if the number of moles of gaseous products is less than the number of moles of gaseous reactants) because the relationship between enthalpy and internal energy change depends on the change in the number of gaseous moles.
