Redox reactions play a pivotal role in chemistry and biology. The values of standard redox potential () of two half-cell reactions decide which way the reaction is expected to proceed. A simple example is a Daniel cell in which zinc goes into solution and copper gets deposited. Given below are a set of half-cell reactions (acidic medium) along with their (V with respect to normal hydrogen electrode) values. Using this data, obtain the correct explanations for the questions given below.
