Question

______________ and suitable catalyst are required to promote high rate of electrode processes.

(a) Lower temperature

(b) Higher temperature

(c) Moderate temperature

(d) Very low temperature

The question was posed to me by my college director while I was bunking the class.

This is a very interesting question from Fuel Cells in chapter Corrosion, Electrolysis, Fuel Cells and Batteries of Engineering Chemistry II

Answer 1

Correct answer is (b) Higher temperature

Easy explanation: Higher temperature and suitable catalyst are required to promote the high rate of electrode processes. The reaction at the anode produces electricity and water as by-products. The catalyst lowers the activation energy required, allowing the reaction to proceed more quickly or at a lower temperature.
