5G.21

Postby AlyssaYeh_1B » Sat Feb 22, 2020 1:41 pm

Calculate the equilibrium constant at 25C for each of the following reactions, by using data in Appendix 2A:
(a) the combustion of hydrogen: 2H2(g) + O2(g) <--> 2H2O(g)
(b) the oxidation of carbon monoxide: 2CO(g) +O2(g) <--> 2CO2 g)
(c) the decomposition of limestone: CaCO3(s) <--> CaO(s) + CO2(g)

What do I need to do after I calculate the delta G values for these reactions?

You can find the K using the delta g value and the delta G0 value. The van't hoff equation may help.

I would use the equation: G=-RTlnK. You calculate G using appendix 2A, and solve for K.
