**Question 4: Analyze the Following Electrochemical Reactions** Consider the reactions given below: 1. \( \text{Zn}^{2+} + 2e^- \rightarrow \text{Zn} \) with a potential of \(-0.76 \, \text{V}\) 2. \( \text{Cr}^{3+} + 2e^- \rightarrow \text{Cr} \) with a potential of \(-0.91 \, \text{V}\) **Question:** How many coulombs were expended in the reaction? **Options:** (a) 2 (b) 4 (c) 96500 (d) 193000 **Discussion:** The problem presents two electrochemical half-reactions along with their respective standard reduction potentials. The task is to determine the amount of electric charge, in coulombs, expended during the reaction. Options listed include values representing possible charges based on electron transfer calculations in typical electrochemical processes.
