Enthalpy Change Calculation

< Prev
Next >

2Ba(s) + O2(g) → 2BaO(s)     deltaH = -1107.0 kJ

Ba(s) + CO2(g) + ½O2(g) → BaCO3(s)     deltaH = -822.5 kJ

Given the thermochemical data above, calculate delta H for the following reaction:

BaCO3(s) → BaO(s) + CO2(g)

A

-1929.5 kJ

B

+269.0 kJ

C

-284.5 kJ

D

+537 kJ

E

-1376.0 kJ
