Question

I NEED HELP PLEASE, THANKS! :)

Answer 1

Answer:

the answer is K=[CaCO2][H2]4[CaO][CH4][H2O]2

and I think it's right but if it's wrong Im sorry

Answer 2

Answer:

$K=\frac{[CaO][CH_{4}][H_{2}O ]^{2} }{[CaCO_{2}][H_{2}]^4 }$

Explanation:

The equilibrium expression is the K value equal to the product of the concentrations of the products over the product of the concentrations of the reactants.  If there is a coefficient in front of the compound, raise the molecule to that power.

Since K is big, more product is expected.  This is because of mathematic principles.  A large numerator with a small denominator will produce a large number.
