If `DeltaH` is the enthalpy change and `DeltaU` the change in internal energy accompanying a gaseous reaction, thenA. `DeltaH` is always greater than `DeltaE`B. `DeltaH lt DeltaE` only if the number of moles of products is greater than the number of moles of the reactantsC. `DeltaH` is always less than `DeltaE`D. `DeltaG lt DeltaE` only if the number of moles of products is less than the number of moles of the reactants |

Answer» Correct Answer - D Reactions in which there is a decrease in the number of moles of the gaseous components , i.e, `Deltan_(g)` is negative , the enthalpy change `(DeltaH)` is lesser than the internal energy change `(DeltaE)` . Reaction in which there is a increase in the number of moles of gaseous components i.e., `Deltang` is positive , the enthalpy change in greater than the internal energy change. `DeltaH-DeltaE+ Deltan_(g)RT` |
