Answer
Please see the work below.
Work Step by Step
The first electron affinity is the energy released in the process of adding one electron to the neutral sulfur atom. Electron affinity is a measure of the attraction between the nucleus and the newly added electron. The higher the attraction the more positive the value for electron affinity.
If the electron affinity value is negative then there must be repulsion not attraction.
When the second electron is added you have to put energy in, rather than energy being released. For the first electron affinity, we were adding an electron to a neutral atom, but now we are adding a negative electron to a negative ion, so they will repel each other. To overcome this electrostatic repulsion, energy must be added in.
