Determine in which direction the reaction 3A(g) + B(s) ⇌ C (g) + D (g) will shift when the amount of B is tripled.

Question

Answer choices

Remains at Equilibrium

None of the above

Up

Right

Left

Answer 1

3A(g) + B(s) <==> C(g) + D(g)

Since B is a solid, changing the amount of B will not affect the equilibrium as it is not included in the Keq expression: K = (C)(D) / (A)³
