1. A reactor for carrying out a chemical reaction, comprising:
a reactor vessel comprising a first region and a second region; and
one or more reaction tubes, wherein a number of tube sections of the one or more reaction tubes in each case run between the first region and the second region;
wherein:
for the electrical heating of the tube sections, the tube sections in the first region in each case are electrically connected to current connections (U, V, W) of a current source by means of flexible connection elements;
current feed arrangements are provided in the first region of the reactor, to which in each case one or in each case one group of the tube sections are electrically connected, and which each comprise one or more contact passages that in each case adjoins or adjoin at least one of the tube sections in the first region;
a wall of the contact passages in each case is connected to a current feed element that has a rod-shaped section that runs at a wall passage through a wall of the reactor vessel; and
the rod-shaped sections of the current feed elements are in each case guided during operation in a longitudinally movable manner in their respective wall passages through the wall of the reactor vessel.
