We have that ##\Delta G = -RT\ln K##. This is in my lecture notes. However, it does not specify whether ##K## is ##K_c## or ##K_p##. Fair enough, I assumed that it could be both. However, when writing out the definitions of ##K_p## and ##K_c##, and using the fact that ##P=CRT##, where ##C## is the concentration, defined as ##n/V##, I noted the fact that ##K_p=K_c(RT)^{\Delta n}##.
So let's say $$\Delta G = -RT\ln K_p = -RT\ln K_c$$ It is clear that this equation cannot be true, right? As you get an extra factor of ##-RT\Delta n \ln(RT)## on one side. Where am I going wrong?
