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.
