For the reaction n2(g) + 3h2(g) 2nh3(g), what will happen if more ammonia gas is added? a.)there will be a shift toward the products. b.)the value for keq will change. c.)there will not be a shift in equilibrium. d.)there will be a shift toward the reactants.

The correct answer is option d.

Explanation:

Any change in the equilibrium is studied on the basis of Le-Chatelier's principle.Whenever we increase the concentration of any species in an equilibrium ,there is a shift in an equilibrium in the direction where decrease in concentration is taking place.

So, when we add ammonia gas into the system , equilibrium will get shift in backward direction that is towards reactants.

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
