2CaSO4(s)→2CaO(s)+2SO2(g)+O2(g)⋅∆H>0
Above equilibrium is established by taking sufficient amount of CaSO4(s) in a closed container at 1600K. Then which of the following may be correct option (Assume that CaSO4 is present in the container in each case)

Moles of CaO(s) will increase with the increase in temperature.
If the volume of the container is doubled at equilibrium then partial pressure of SO2(g) will change at new equilibrium.
If the volume of the container is halved partial pressure of O2(g) at new equilibrium will remain same
If two moles of the He gas is added at constant pressure then the moles of CaO(s) will increase
