The standard cell potential of cell, $\mathrm{Pt\,|\,H_2(g)\,|\,HBr(aq)\,|\,AgBr(s)\,|\,Ag(s)}$, was measured over a range of temperatures, and the data was fitted as $E^{0}(\mathrm{Volt})=0.01-1\times10^{-4}(T-298)-2\times10^{-6}(T-298)^{2}$ The standard reaction entropy ($\mathrm{J\,K^{-1}\,mol^{-1}}$) and enthalpy ($\mathrm{kJ\,mol^{-1}}$) at $298\,K$ are
(a)-9.65 and -3.84
(b)-3.84 and -9.65
(c)-18.3 and-7.68
(d)-7.68 and -18.3
