MHT CET 2025 Chemistry question
If standard reduction potential () of ( | ), ( | ), ( |) and ( | ) are -2.37 V, +0.79 V, -0.76 V and +0.34 V respectively. Which of the following reaction is spontaneous?
Answer: (C)
Solution
A reaction is spontaneous if (cathode = species reduced, anode = species oxidised). (A) Zn is oxidised, reduced: V, non-spontaneous. (B) Ag is oxidised, reduced: V, non-spontaneous.
