A mixture containing 3.7 moles of NO and 0.88 mole of CO2 was allowed to react in a flask at a certain temperature according to the equation NO(g) + CO2(g) ⇆ NO2(g) + CO(g) At equilibrium, 0.15 mole of CO2 was present. Calculate the equilibrium constant Kc of this reaction.

Most likely a is the answer - because  you generate   38 atp's but also consume an atp.   each atp gives approx. less than 4 kcal so probably a is the closest answer.

The density would be 1.622

There is no reason to think the results are biased or not conducted properly but you should not assume the results are correct just because they were done in a laboratory so the answer would be c. it is likely to be reliable because the results support the conclusion presented.

Ithink its called the coefficent.
