8 / 10

Look at the chemical equation below.

2NaHCO3(s)=> Na2CO3(s)+ H2O(g)+ CO2(g)

Using your answers to Questions 1 and 2, calculate the Gibbs Energy change, ΔG, for the process if it is carried out in an oven at 100oC.

If this question is from a Random Retrieval, you can also carry out this calculation by first working out values for ΔSƟ and ΔHƟ by selecting the appropriate data from the ‘Selection of Thermodynamic Data’ in TOOLS.
