4. The chemical equation shows CaCO3 being heated. Write a statement which best describes
the mass of the products if 100 g of CaCO3 is heated

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?

0.042

0.42

2.4

24

the answer is a! (2.9 x 10^-18 j) hope i could someone. : )
