Consider the following reaction at `1000^(@)C`
(A) `Zn (s) + (1)/(2) O_(2) (g) rarr ZnO(s), Delta G^(Ө) = - 360 kJ mol^(-1)`
(B) `C (s) + (1)/(2) O_(2) (g) rarr OO(g), Delta G^(Ө) = - 460 kJ mol^(-1)`
Choose the correct statement at `1000^(@)C`

Options

A. Zinc can be oxidised by carbon monoxide
B. Zinc oxide can be reduced by graphite
C. Both statement (a) and (b) are true
D. Both statement (a) and (b) are false

Answer

B

Explanation

At ` 1000^(@)C` zinc oxide can be reduced by graphite . `ZnO+C to Zn + CO `
