INTEGER+4 / -12023
Consider the following reaction approaching equilibrium at 27\(^\circ\)C and 1 atm pressure
\(\mathrm{A+B}\) \(\mathrel{\mathop{\kern0pt\rightleftharpoons} \limits_{{k_r} = {{10}^2}}^{{k_f} = {{10}^3}}}\) \(\mathrm{C+D}\)
The standard Gibb's energy change \(\mathrm{(\Delta_r G^\theta)}\) at 27\(^\circ\)C is (\(-\)) ___________ kJ mol\(^{-1}\) (Nearest integer).
(Given : \(\mathrm{R=8.3~J~K^{-1}~mol^{-1}}\) and \(\mathrm{\ln 10=2.3}\))
