N_(2(g))+O_(2(g))rarr 2NO_(2(g))-Q is ……………..

Given that : 2CO_((g))+O_(2(g))rarr2CO_(2(g)),DeltaH^(@)=-P kJ C_((s))+O_(2(g))rarr CO_(2(g)), DeltaH^(@)=-Q kJ the enthalpy of formation of carbon monoxide is :

In the reaction, 2NO(g)+O_(2)(g)rarr2NO_(2)(g) , the rate to change of concentration of NO is
