QJEEM22Chf4b1: JEE Main 2022 Chemistry - Class 11 JEEM22Chf4b1 Solution: Which of the following relation is not correct?

Which of the following relation is not correct?

Multiple Choice Options

  • A ΔH=ΔU−PΔV\Delta \mathrm{H}=\Delta \mathrm{U}-\mathrm{P} \Delta \mathrm{V}
  • B ΔU=q+W\Delta \mathrm{U}=\mathrm{q}+\mathrm{W}
  • C ΔSsys +ΔSsurr ⩾0\Delta \mathrm{S}_{\text {sys }}+\Delta \mathrm{S}_{\text {surr }} \geqslant 0
  • D ΔG=ΔH−TΔS\Delta \mathrm{G}=\Delta \mathrm{H}-\mathrm{T} \Delta \mathrm{S}

Step-by-Step Verified Solution

If U+Pv\mathrm{U}+\mathrm{Pv} (By definition)

Δ14=ΔU+Δ(Pr)\Delta 14=\Delta \mathrm{U}+\Delta(\mathrm{Pr}) at constant pressure

ΔH=ΔU+PΔV\Delta \mathrm{H}=\Delta \mathrm{U}+\mathrm{P} \Delta \mathrm{V}
