How does a decrease in partial pressure for all species in this system affect the equilibrium of the following reaction? 2H2(g)+O2(g)⇌2H2O(g) Choose one: A.The reaction shifts to the right, because there are 3 moles of gas on the left and only 2 moles on the right. Decreasing the partial pressures means that the number of moles must decrease. B.The reaction shifts to the left, because there are 3 moles of gas on the left and only 2 moles on the right. The lower partial pressures favors the collection of molecules that take up the most space.

Question
How does a decrease in partial pressure for all species in this system affect the equilibrium of the following reaction?
2H2(g)+O2(g)⇌2H2O(g)
Choose one:
A.The reaction shifts to the right, because there are 3 moles of gas on the left and only 2 moles on the right. Decreasing the partial pressures means that the number of moles must decrease.
B.The reaction shifts to the left, because there are 3 moles of gas on the left and only 2 moles on the right. The lower partial pressures favors the collection of molecules that take up the most space.
C.The reaction will not shift at all, because both the products and reactants are gases.
D. The exothermic reaction will be favored; this is the forward reaction.
C. It is impossible to tell without knowing the volume of the vessel and the temperature of the reaction.
