qn on chemical equilibrium

yl_c SG

Hi, need some help here..

Q. At 25 deg. C, K(c) = 1.6 X 10^24 for the reaction CaO (s) + CO2 (g) <---> CaCO3 (s). Use the value of K(c) to estimate the extent of this reaction. Verify your estimate by calculating the concentration of CO2 gas that is in equilibrium with solid CaO and solid CaCO3 at 25 deg. C

And are there any good books/resources for studying chemistry at the polytechnic level? The only qns i have to practise are my tutorial worksheets :/

Thanks

Since the value of Kc is very high, the concentration of CO2 is very very negligible. And the reaction is almost complete.

We can say for every molecule of CO2 left with, 1.6 X 10^24 CaCO3 units are formed.

There are so many online resources. Find some nice chemistry material at adichemistry. Search on Google for adichemistry.
