Wink Energy problem

Hi, I am not able to solve this problem. Any help?
Avogadro constant: N=6.022*10^23(Number of atoms in 12 grams of atom)
Calculate the energy in joules and power in watts when 2 kg of coal(Consisting only of carbon) is burnt for 1.5 hour. Assuming the equation:C+O2->CO2+4eV.
And anyone please explain this equation.
