Compute the heat released in the reaction

Reference no: EM13170574

Calculate the heat released (kJ) in the reaction of 2.20 g of sulfur dioxide gas and excess oxygen gas to form sulfur trioxide gas:

2SO2(g) + O2(g) ® 2SO3(g)

Given:

S(s) + O2(g) ® SO2(g) DH = -299 kJ/mol

S(s) + 3/2O2(g) ® SO3(g) DH = -395 kJ/mol
