Constant

[Jina Kwon]

What R constant do we use fort this equation?

[Tyler Angtuaco 1G]

I would guess the 8.314 J·K-1·mol-1 since enthalpy is in joules and temperature is in kelvin. The units would then cancel, which makes sense because the equilibrium constant has no units.

The R constant depends on the units you are given and/or the units you want to end up with. For instance, if you are given volume in liters and pressure in atm, then use the constant with those units in it (8.206x10^-2). If you are calculating entropy, use the 8.314 R constant since you want entropy to be in J/K. Hope this helps!

A good way to figure out which R to use it to see what units you need to cancel in order to get the desired units
