A) Zinc can be oxidized by CO
B) Zinc oxide can be reduced by C
C) Both statements [a] and [b] are true
D) Both statements [a] and [b] are false
Correct Answer: B
Solution :
[b] Carbon is the suitable reducing agent for zinc oxide at \[1000{}^\circ C\] as \[\Delta {{G}^{o}}_{CO}-\Delta {{G}^{o}}_{ZnO}\] is negative. \[\Delta {{G}^{o}}_{CO}-\Delta {{G}^{o}}_{ZnO}=-\,400-(-360)=-\,40\]KJ/mol.You need to login to perform this action.
