PYQ NEET- Chemical Thermodynamics L-2

Question: Which amongst the following options is the correct relation between change in enthalpy and change in internal energy?#

A) $\Delta \mathrm{H}=\Delta \mathrm{U}+\Delta \mathrm{n}_{\mathrm{g}} \mathrm{RT}$

B) $\Delta \mathrm{H}-\Delta \mathrm{U}=-\Delta \mathrm{nRT}$

C) $\Delta \mathrm{H}+\Delta \mathrm{U}=\Delta \mathrm{nR}$

D) $\Delta \mathrm{H}=\Delta \mathrm{U}-\Delta \mathrm{n}_{\mathrm{g}} \mathrm{RT}$

Answer: $\Delta \mathrm{H}=\Delta \mathrm{U}+\Delta \mathrm{n}_{\mathrm{g}} \mathrm{RT}$#

Solution:#

$\Delta \mathrm{H}=\Delta \mathrm{U}+\Delta \mathrm{n}_{\mathrm{g}} \mathrm{RT}$
