Redox Reactions And Electrochemistry Question 90
For the reactions, $ C+O_2\to CO_2;\Delta H=-393,kJ $ $ 2Zn+O_2\to 2ZnO;\Delta H=-412,kJ $ [AIEEE 2002]
Options:
A) Carbon can reduce $ Zn $
B) Oxidation of carbon is not feasible
C) Oxidation of $ Zn $ is feasible
D) $ Zn $ cannot oxidise carbon
Show Answer
