Will you be repairing & reusing the existing rung, or making a replacement ??

Now let us retract the foreskin of misconception and apply the wire brush of enlightenment.

Welcome to the forum! Hope we can help.
If you can, try and post a picture. Use one of these on-line photo sharing sites. Copy the URL link to the photo and copy it onto the pop-up after you click on Image.
Rocking chairs can be tricky. The first thing I'd do is see if there's any way the rung could be repaired in place. If it's broken straight across the grain----it would be pretty hard to do, but if it's split along long grain, you have a chance.
Otherwise, first thing is to find out if any nails or dowels were used at the M&T joints of the rung. You'll need to remove the nail or drill out the dowel.
If it's either hide or regular wood glue, your best shot is holding a heat gun on the joint and try and wiggle the joint apart. However, it might be that other rungs are keeping the joint tight as well, which will also have to be loosened up as well. If you have any parallel jaw clamps where the head can be reversed, you can use it as an expansion tool to spread the legs or whatever is attached to the rung.

If the other joints are all good, it might be better not to try to disassemble the chair. Once you remove both ends of the broken rung, turn a new one to match. Usually rungs have a tenon on both ends. For the new one only make one end with a tenon; make the other end flat, or at whatever angle the original is but without a tenon in any case. Then drill a hole in that end the combined length of the tenon on the other end and the depth of the hole in the leg, plus a little. On the bottom of the rung where you bored the mortise, route a 1/8" slot about 1/4" long at about mid length of the mortise. Lastly, make a tenon to fit in the chair leg and rung mortise. Note that the mortise needs to be at least as large in diameter as the hole in the rung for this to work. Also, the tenon needs to be able to slide in pretty easily for this method to work, and either drill a small hole lengthwise through the tenon or put a couple of shallow grooves along the outside edge so that the glue can pass along it as you slide it into place. Now apply epoxy or a slow setting yellow glue into the loose tenon hole and rung, then slide the loose tenon into the hole in the rung until it's flush with the end. Then glue the end with the fixed tenon in place. Finally, align the loose tenon end with the hole in the leg, then reach up through the routed slot with an ice pick and slide the loose tenon into the rung hole. Put a clamp on it, if needed, and you're done. It sounds complicated but it's really not too hard to do, and beats taking apart a chair that doesn't want to or need to be.

OK, then steam bend or bandsaw one. You can still use the process I described above to install it without having to disassemble the chair.
