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`

A

"Zinc" can be oxidized by `CO`

B

"Zine"oxide can be readuced by `C`

C

Both (1) and (2) are true

D

Both (1) and (2) are false

Text Solution

Verified by Experts

The correct Answer is:
b
Because the net `Delta G` is negative
`ZnO(s) rarr Zn(s) + (1)/(2) O_(2), Delta G = 360 kJ mol^(-1)`
`C(s) + (1)/(2) O_(2)(g) rarr CO(g) , Delta G = - 460 kJ mol^(-1)`
`ZnO(s) + C(s) rarr Zn(s) + CO(g) Delta G = - 100 kJ mol^(-1)`
