Consider the following reaction where Kc = 0.159 at 723 K. N2(g) + 3H2(g) 2NH3(g) A reaction mixture was found to contain 1.97×10-2 moles of N2(g), 3.82×10-2 moles of H2(g) and 5.27×10-4 moles of NH3(g), in a 1.00 liter container. Is the reaction at equilibrium? If not, what direction must it run in order to reach equilibrium? The reaction quotient, Qc, equals 9.63x10^4 . The reaction b A. must run in the forward direction to reach equilibrium. B. must run in the reverse direction to reach equilibrium. C. is at equilibrium.

The reaction moves to the left. To the reactants side

Explanation:

The reaction given by the problem is:

Therefore the equilibrium constant expression would be:

With the values equilibrium concentration values we can calculate the quotient "Qc", so:

In this case Qc>Kc we will have more amount of product. Therefore, the reaction will go to the left to reach the equilibrium.

I hope it helps!

b. acid is the correct answer @jayxboof all social media

acid : acids are those which accepts an electron-pairs.

base : bases are those which donates ab electron-pairs.

alkali : it is a base that dissolves in water. it is basically a base and the ph greater than 7.

hydroxide ion : it is a poly-atomic ion which is negatively charged.
