How do you convert kcal to kJ mol?
To convert a kilocalorie measurement to a kilojoule measurement, multiply the energy by the conversion ratio. The energy in kilojoules is equal to the kilocalories multiplied by 4.184.
What is the difference between kcal mol and kJ mol?
In SI units, one kilocalorie per mole is equal to 4.184 kilojoules per mole (kJ/mol), or 6.9477×10−21 joules per molecule, or 0.043 eV per molecule. At room temperature (25 °C, 77 °F, or 298.15 K) it is equal to 1.688 units in the kT term of Boltzmann’s equation.
What is the bond enthalpy of c2h4?
| Bond | C−C | H−H |
|---|---|---|
| Bond Enthalpy | 336.81 kJ / mol | 431.79 kJ / mol |
How do you convert calories to kcal?
To convert a calorie measurement to a kilocalorie measurement, divide the energy by the conversion ratio. The energy in kilocalories is equal to the calories divided by 1,000.
Is kcal and kJ the same?
Checking calories in food The calorie content is often given in kcals, which is short for kilocalories, and also in kJ, which is short for kilojoules. A kilocalorie is another word for what’s commonly called a calorie, so 1,000 calories will be written as 1,000kcals. Kilojoules are the metric measurement of calories.
What is the enthalpy change of C2H4 H2 C2H6?
The enthalpy change for the reaction, C2H4(g) + H2(g) → C2H6(g) is – 620 J when 100 mL of ethylene and 100 mL of H2 react at 1 bar pressure.
What is the enthalpy of formation of H2?
12.001. 0. Hydrogen. H2(g) 2.016.

How do you convert kJ to kJ in calories?
Kilojoules to thermochemical / food kilocalories 1 kcal th = 4.184 kJ The energy in kilocalories E(kcal-th) is equal to the energy in kilojoules E(kJ) divided by 4.184: E(kcal) = E(kJ) / 4.184
What is the energy in international kilocalories E (kcal-it)?
The energy in international kilocalories E(kcal-IT) is equal to the energy in kilojoules E(kJ) divided by 4.1868: E(kcal-IT) = E(kJ) / 4.1868
