Consider the following reaction at `1000^(@)C`
`(A) Zn_((s))+(1)/(2)O_(2(s))+ZnO_(s),DeltaG^(0)=-360kJ"mole"^(-1)`
(B) `(B) Cn_((s))+(1)/(2)O_(2(g))to CO_(s),DeltaG^(0)=-460kJ"mole"^(-1)`
choose the correct statement at `1000^(0)C`

A

Zinc can be oxidised by CO

B

Zinc oxide can be reduced by C

C

Both satement (a) and (b) are true

D

Both statement (a) and (b) are false

Text Solution

Verified by Experts

The correct Answer is:
B
`ZnO+C to Zn+CO,`
`" " Delta_(Rx^(n))^(@)=-460+360 lt 0 ("Spontaneous")`
