You can use either a 2-inch or 2.5-inch conduit based on the fill space you intend to occupy inside the conduit. New code requirements require two ground rods for regions with high soil electrical resistance. Because the rod or the rebar is technically a grounding electrode, this ground wire is correctly called a grounding electrode conductor. So, a 2 conduit will suffice, or you can upsize to 2.5 if you wish for ease of pulling. This bonding creates a path with such low impedance (resistance) that fault currents flow along it, quickly tripping breakers or fuses and interrupting power.
