Re: R constant
You'd want to use the value 8.314 J*K^-1*mol^-1 for this equation. The easiest way to tell is to look at the units of everything else in the equation and see what needs to be cancelled. Hope this helps.

Re: R constant
You use R= 8.314 J/(Kmol). If you look at the units, we know that delta G and delta G nought are in J/mol. Therefore, RTlnQ needs to be in J/mol, too. When R is in J/(Kmol) and temperature is K, then the final product of RxT is in J/mol, which is what you want.

Re: R constant
Usually, look for whetehr Joules are used in the question, and that would mean that you would use 8.314 J/(K x mol.)

Re: R constant
Typically 8.314JK^-1mol^-1 is used, but it really depends on the units of other variables that are given.

Re: R constant
Typically, to determine what value of R to use, you look at the units being used. In this scenario, R would equal 8.314 J/(Kmol)!
Re: R constant
it will depend on the units given to you in the question. you can use either but its more efficient to use the one matching the questions units so you wont have to convert anything
