1. A reactor for carrying out a chemical reaction, the reactor comprising:
a reactor vessel; and
one or more reaction tubes;
wherein;
one or more power input elements are guided into the reactor vessel for electrical heating of the one or more reaction tubes;
the one or more power input elements each have a rod-shaped section, and the rod-shaped section or sections each run in a respective wall passage through a wall of the reactor vessel;
a connection chamber into which the rod-shaped section(s) project is located outside the reactor vessel and adjacent to the wall of the reactor vessel in which the wall passage(s) are formed;
gas feed means are provided, which are set up to apply inerting gas to the connection chamber; and
the wall passage(s) with the rod-shaped section(s) received therein in a longitudinally-movable manner are designed to be gas-permeable so that at least a portion of the inerting gas fed into the connection chamber flows into the reactor vessel.
