Answer:The standard Gibbs energy change at 300K for the reaction 2A⇔B+C is 2494.
Step-by-step explanation:
ΔG = free energy at any moment.
ΔGo = standard-state free energy.
R is the ideal gas constant = 8.314 J/mol-K.
T is the absolute temperature (Kelvin)
lnQ is natural logarithm of the reaction quotient
