Do we only use kJ/mol if we have been given the value or calculated a reaction with only one mole of a particular reactant?

You use KJ/mol for standard values like standard enthalpy of formation or standard Gibbs free energy because standard conditions are ones for 1 mol of a substance. This is any value with the little (°) next to it. Ex: delta H°, delta G°

Additionally, if you evaluate the equation to solve for the variable, you can determine what units you need to use.
