Use the SMALLEST INTEGER coefficients possible and put the energy term (including the units) in the last box on the appropriate side of the equation. If a box is not needed, leave it blank.

Question

When I₂(g) reacts with Cl₂(g) to form ICl(g) , 26.8 kJ of energy are evolved for each mole of I₂(g) that reacts.

Write a balanced thermochemical equation for the reaction with an energy term in kJ as part of the equation. Note that the answer box for the energy term is case sensitive.

Use the SMALLEST INTEGER coefficients possible and put the energy term (including the units) in the last box on the appropriate side of the equation. If a box is not needed, leave it blank.

Answer 1

Balanced equation: I₂(g) + Cl₂(g) ==> 2 ICl + 26.8 kJ (heat is evolved = exothermic = on product side)
