CH₄(g) + H₂O(g) ⇋ CO(g) + 3H₂(g) ΔH = +210 kJ mol⁻1Equilibrium will move to the right because the forward reaction is endothermicEquilibrium will move to the right because the forward reaction is exothermicEquilibrium will move to the left because the forward reaction is exothermicEquilibrium will move to the left because the forward reaction is endothermicQuestion 6 of 10 Loading... 7. Explain, in terms of making and breaking bonds, why a reaction could be endothermicThe bonds in the reagents are weaker than the bonds in the productsThe energy needed to break the bonds is more than the energy released to make the bondsBreaking the bonds is more favourable than making themThe energy needed to break the bonds is less than the energy released to make the bondsQuestion 7 of 10 Loading... 8.
