Ineed fast! will mark ! how will this system at equilibrium be affected by each of the conditions stated here? 2h(little 2)(g)+o(little 2) (g)< -> 2h(little 2)o(g) + heat (a) removal of h(little 2) o = a. system will shift towards the reactants b. system will shift towards the products c. system will is at equilibrum (b) addition of o(little 2) = a. system will shift towards the reactants b. system will shift towards the products c. system will is at equilibrum (c) decrease in pressure = a. system will shift towards the reactants b. system will shift towards the products c. system will is at equilibrum (d) increase in temperature a. system will shift towards the reactants b. system will shift towards the products c. system will is at equilibrum

(A). System will towards the products.

When H₂O is removed, the concentration of products will be low. Then the equilibrium of the system will be broken. Hence, according to the Le Chatelier's principle, system will try to become equilibrium by enhancing the forward reaction. 

(B). System will shift towards the products.

Addition of O₂ will increase the concentration of reactants. Then to maintain the equilibrium the O₂ should be decreased. To do that the system will shift towards the products. When products are increased, the consuming of O₂ will be high. 

(C). System will shift towards the reactants.

When pressure is decreased, according to the Le Chatelier's principle, system will try to increase the pressure to maintain the equilibrium. There are 2 moles of H₂ and 1 mole of O₂ as reactants. Hence, altogether there are 3 moles of molecules as reactants but 2 moles of molecules as products. When the number of moles of molecules is high, then the pressure is high. Hence, to increase the pressure, system will shift towards the reactants.

(D). System will shift towards the reactants.

The given reaction is an exothermic reaction since it produces heat. When the temperature is high, system will try to lower the temperature. Since forward reaction is exothermic, the backward reaction is endothermic. When there is increase in temperature, system will shift towards the reactants because endothermic reactions decrease the temperature.
