WAEC Chemistry 2011 Objective — Question 38

Consider the following electrochemical cell notation: M(s)/M²⁺(aq)//H⁺(aq)/H2(g). The value of the electrode potential is positive when

• A. A. electrons flow from the metal electrode, M(s) to hydrogen electrode, H2(g)Correct
• B. B. electrons flow from hydrogen electrode, H2(g) to metal electrode, M(s)
• C. C. the flow of current is high
• D. D. there is equilibrium between the flow of electrons from the hydrogen electrode to metal electrode
