Correct answer is option C i.e. <span>The equilibrium shifts to the right.
Reason:
Following reaction is involved in present case:
N2 (g) + 3H2 (g) </span>⇄<span> 2NH3(g)
Now, according to </span><span>Le Chatelier's principle, if pressure is increased/decreased in system, the reaction equilibrium will move in direction to minimize this effect. So, if H2 is added in reaction system, it will increase pressure of reaction system. Hence, equilibrium will shift towards right, so as to minimize the effect of increasing pressure. </span>
I would say your answer is C, or the last one. Hope it helps
We know that as we move from left to right across a period in a modern periodic table, electronegativity increases ( i.e., gaining of electrons from an atom ). So Magnesium(Mg) who has an atomic no. as 12 will not gain electrons but share/transfer electrons to Neon(Ne).
I hope this answer will help you...If it does then mark my answer as the brainliest!!!
Byee!!!
