Exhibit 17-2
The following question(s) pertain to an electrochemical system in which a 1.5 V battery supplies a current of 0.5 amps for 18 hours to an iron electrode immersed in a solution of nickel nitrate.
Refer to Exhibit 17-2. What is the amount of electrical work done by the battery?

Question

Quizplus · Accepted Answer

The electrical work done by the battery can be calculated using the formula: Work = Voltage x Current x Time. Here, Voltage = 1.5 V, Current = 0.5 A, and Time = 18 hours (which is 18 x 3600 seconds). Therefore, Work = 1.5 x 0.5 x 18 x 3600 = 72900 J.
