According to the equation
-ΔG/RT = log K
Then if the ΔG is negative then -ΔG/RT is positive as T and R r always . In that case K will have a real positive value greater than 1. Otherwise it will have the value less than 1 when ΔG is negative .
Karteek Ravindra Bhat
Because a reaction with ΔG<0 is spontaneous thus eq. constant must be greater than 1 so that the reaction moves forward.It can also be analysed using formula
ΔG=2.303RTlogK

In the reaction A + 2B ⇌ 2C, if 2 moles of A, 3 moles of B and 2 moles of C are placed in a 2 L flask and
the equilibrium concentration of C is 0.5 mol/L. The equilibrium constant (KC) for the reaction is.....and please tell how you know that the reaction is going forward .. imean how to calculate the reaction quotient ???
