নিচের কোন সমীকরণটি সঠিক?

$\mathrm{K}_{\mathrm{c}}=\mathrm{K}_{\mathrm{p}}(\mathrm{RT})^{\Delta \mathrm{n}}$

$\mathrm{E}_{\text {cell }}=\mathrm{E}_{\text {cell }}^{\circ}+\mathrm{RT} \ln \frac{[\text { Product }]}{[\text { Reactant }]}$

$\mathrm{E}=\mathrm{h} \frac{\lambda}{\mathrm{c}}$

$\mathrm{pH}-\mathrm{pOH}=\mathrm{pK}_{\mathrm{w}}$

$\mathrm{E}_{\text {cell }}=\mathrm{E}_{\text {cell }}^{\circ}+\mathrm{RT} \ln \frac{[\text { Reactant }]}{[\text { Product }]}$
