AS levelsOh sorry. R u studying a levels
Can someone please help me with this:
Given CO(g) + 1/2 O2(g) → CO2(g) ΔHo = –283 kJ mol–1 H2(g) + 1/2 O2(g) → H2O(l) ΔHo = –286 kJ mol–1H2O(g) → H2O(l) ΔHo = –44 kJ mol–1what is the change in enthalpy, ΔHo, for the following reaction?
CO2(g) + H2(g) → CO(g) + H2O(g)
A –525 kJ mol–1 B –41 kJ mol–1 C +41 kJ mol–1 D +525 kJ mol–1
I am getting B but apparently the correct ans is C.
I don't know where i went wrong so if someone can tell i'd be very grateful.
