<span>The chemical reaction of a reversible reaction is actually
governed by Le Chatelier’s principle. It states that when more reactants are
introduced into the system, the reaction will proceed forward to create more
products. So since Hydrogen is a reactant and Nitrogen is also reactant so
adding more Hydrogen makes more products hence reducing the Nitrogen
concentration.</span>
Answer:
the real tricky one question
Explanation:
Answer:

Explanation:
We have the reactions:
A: 
B: 
Our <u>target reaction</u> is:

We have
as a reactive in the target reaction and
is present in A reaction but in the products side. So we have to<u> flip reaction A</u>.
A: 
Then if we add reactions A and B we can obtain the target reaction, so:
A: 
B: 
For the <u>final Kc value</u>, we have to keep in mind that when we have to <u>add chemical reactions</u> the total Kc value would be the <u>multiplication</u> of the Kc values in the previous reactions.
