`C + 1/2 O_2 to ………..`

The plot shows the variation of - In K_p versus temperature for the two reactions. M(s) + (1)/(2) O_2 (g) rarr MO (s) and C(s)+ (1)/(2) O_2(g) rarr CO(s) Identify the correct statement ,

Consider the following reaction at 1000^circ C (A). Zn_((s)) + 1 / 2 O_2 (g) rarr ZnO_ ((s)) , Delta G^circ=-360 kJmol^-1 (B). C_((grap))+1 / 2 O_2 (g) rarr CO_ ((g)) , Delta G^circ=-460 k Jmol^-1 choose the correct statement at 1000^circ C . : Zinc can be oxidised by carbon monoxide, zinc oxide can be reduced by graphite, both (a) and (b) are flase, both (a ) and (b) are true

Delta G^circ' Vs. T plot in the Ellingham's diagram slopes downward for the reaction : Mg+2 O_2 rarr MgO , 2 Ag+1 / 2 O_2 rarr Ag_2 O , C+1 / 2 O_2 rarr CO , CO+1 / 2 O_2 rarr CO_2
