Changes in pressure for an equilibrium reaction containing a solid/liquid on one side only

Image
2 For a reaction where there is only one solid/liquid present, but gases present as both reactants and products (are there any examples of this type of reaction?): $$ce{A(s) + B(g) <=> C(g)},$$ if pressure is increased, it will favour the formation of the side not containing the solid/liquid ( e.g. the forward reaction favoured ), so as to decrease pressure of system – since one mole of a gas molecules has a considerably lower volume than a mole of any solid or liquid (far more spread out). And the opposite if pressure decreased. E.g. all that is considered is which side the solid/liquid is on, not the moles of gas present on either side . Is this true? physical-chemistry equilibrium pressure share
