Is kj and kj/mol the same
Witryna10 lut 2024 · To add to JB’s answer, the same energy is often expressed as either kJ/mol or kcal/mol. To convert ev/atom to kJ/mol, first convert it to kJ/atom using 1 eV = 1.6021765×10⁻²² kJ (1/1000 of JB’s value for joules) and then multiply by Avogadro’s number 6.0221468×10²³.

WitrynaTherefore, Δ H f ° [O 3 (g)] = +143 kJ/mol. Δ H f ° [O 3 (g)] = +143 kJ/mol. Check Your Learning Hydrogen gas, H 2, reacts explosively with gaseous chlorine, Cl 2, to form hydrogen chloride, HCl(g). What is the enthalpy change for the reaction of 1 mole of H 2 (g) with 1 mole of Cl 2 (g) if both the reactants and products are at standard ... WitrynaIf the units for are given as kJ rather than kJ/mol rxn, and we want for the reaction of 0.10 mol of CO, the procedure is rather strained. First, we need to recognize that the -566.0 kJ actually applies to the consumption of two moles of CO. That seems to imply that we need to divide kJ by moles so that now we have a unit on a per mole basis.
Witryna7 sty 2016 · Re: kJ vs kJ/mol. I think they are essentially describing the same thing, with only a small difference between them. If it's kJ/mol, and you have more than 1 mole of whatever it is, then (depending on the specific problem) you might need to multiply a …
