Thermochemistry

Question

Use bond energy values to calculate the enthalpy change in kJ for the reaction represented in the equation below. Give the quantity and unit, and don't forget the + or - signs.

CH4(g) + H2O(g) → CO(g) +3H2(g)

Answer 1

Give the quantity and unit, and don't forget the + or - signs.

so you should not have any problems in completing the calculation. Make sure that on the reactant(s) side place a positive sign as "cost" of breaking chemical bonds, while product(s) side, negativve sign as "gain" of forming new bonds...

what is the net energy change for the reaction?
