Question

Can you please explain to me how you would regulate the pressure to favor the products in the this equilibrium system.

MgCO3(s)--><-- MgO(s)+CO2(g)
Thank you

Answer 1

An increase in P shifts the equilibrium to the side with fewer mols of gas; therefore, an increase in P shifts it to the left. That means you want to decrease the pressure to shift the reaction to the right.
