Please help i’ve been stuck in this for a while

Explanation:

I got you....so equilibrium constant is written as products/reactants with raising the products and reactants to appropriate powers based on leading coefficients.

For eg: A+2B------->2C+3D  

Keq for this is products/reactions i.e. [(C)^2 (D)^3]/[(A) (B)^2]  you see we raised each product or reactant for leading coefficient (the number in balanced equation) power.

In the question above.....

The keq would thus be   therefore answer is B

answer; natural resources;

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
