Multiple Choice Options

  • A ΔGsystemΔStotal=−T{{\Delta {G_{system}}} \over {\Delta {S_{total}}}} = - T
  • B In isothermal process wreversible{w_{reversible}} = −nRT ln⁡ VfVi- nRT\,\ln \,{{{V_f}} \over {{V_i}}}
  • C In K =ΔHo−TΔSoRTK\, = {{\Delta {H^o} - T\Delta {S^o}} \over {RT}}
  • D K = e−ΔGo/RTK\, = \,{e^{ - \Delta {G^o}/RT}}

Step-by-Step Verified Solution

ΔG∘=ΔH∘−TΔS∘;\Delta {G^ \circ } = \Delta {H^ \circ } - T\Delta {S^ \circ };

         −RT ℓnK=ΔH∘−TΔS∘\,\,\,\,\,\,\,\,\, - RT\,\ell nK = \Delta {H^ \circ } - T\Delta {S^ \circ }

ℓnK=−ΔH∘−TΔS∘RT\ell nK = - {{\Delta {H^ \circ } - T\Delta {S^ \circ }} \over {RT}}
