Expert Answer
According to Le Chatelier's principle of Chemical-equilibrium, At equilibirium state, When pressure increases then reaction shifts in the direction where number of moles are less and When pressure decreases then reaction shifts in the direction of higher number of moles.
In case of decomposition of CaCO3 -
In closed vessel, there is no chaange in number of moles, So pressure will remain constant at equilibrium.
