Consider the following system, which is at equilibrium,
3C(s) + 3 H2(g) mc020-1.jpg CH4(g) + C2H2(g)
The result of removing some C(s) from the system is that
a) more CH4(g) and C2H2(g) are produced to replace that which is removed.
b) Kc decreases.
c) more C(s) is produced.
d) no further change occurs.
The correct answer is d. As long as some carbon is present, adding or removing carbon will not affect the equilibrium.
