# When S(s-rhombic) reacts with CO(g) to form SO2(g) and C(s-graphite) -.docx

When S(s,rhombic) reacts with CO(g) to form SO2(g) and C(s,graphite) , 75.8 kJ of energy are evolved for each mole of S(s,rhombic) 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.
Solution
The reaction
S + 2CO = SO2 + 2C
Energy data --> H = -75.8
S(s,rhombic) + 2CO(g) = SO2(g) + 2C(s) Hrxn = -75.8 kJ/mol
