Explain the thermo chemical equation for the combustion

Question

The thermo chemical equation for the combustion reaction of half a mole of carbon monoxide is as follows:

1/2 CO₂ (g) + 1/4O₂ (g) --> 1/2CO₂ (g)                 delta H⁰ = -141.49 kJ

Write down the thermo chemical equation for

1. The combustion of 2mol of CO (g)

2. The decomposition of 1 mol of CO₂ (g) to O₂ (g) and CO(g)
