| $(IE_1 + IE_2)$ | $(IE_3 + IE_4)$ |
| $(P)$ $2.45\, KJ/mol$ | $8.82\, KJ/mol$ |
| $(Q)$ $2.85\, KJ/mol$ | $6.11\, KJ/mol$ |
then according to given information the incorrect statements is/are
$C + {O_2} \to C{O_2};\,\Delta H = - 394\,kJ\,mo{l^{ - 1}}$
$2CO + {O_2} \to 2C{O_2};\,\Delta H = - 569\,kJ\,mo{l^{ - 1}}$ The heat of formation of $1\,mol$ of carbon monoxide is thus .....$kJ\,mo{l^{ - 1}}$
