NEETChemistryThermodynamicsMCQ+4 / −1

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

  1. A
    ΔH=ΔU+ΔngRT\Delta \mathrm{H}=\Delta \mathrm{U}+\Delta \mathrm{n_g R T}ΔH=ΔU+Δng​RT
  2. B
    ΔH−ΔU=−ΔnRT\Delta \mathrm{H}-\Delta \mathrm{U}=-\Delta \mathrm{nRT}ΔH−ΔU=−ΔnRT
  3. C
    ΔH+ΔU=ΔnR\Delta \mathrm{H}+\Delta \mathrm{U}=\Delta \mathrm{nR}ΔH+ΔU=ΔnR
  4. D
    ΔH=ΔU−ΔngRT\Delta \mathrm{H}=\Delta \mathrm{U}-\Delta \mathrm{n_g R T}ΔH=ΔU−Δng​RT
