What is the `K_(eq)` expression for the reaction, `C(s)+CO_2(g)to2CO(g)` ?

Write the expression K_p for the reaction : CaCO_3(s) hArr CaO(s) +CO_2(g)

deltaE^(@) is measured at constant volume and deltaH^(@) is measured at constant pressure. For the reaction , 2C(s)+O_(2)(g)to2CO(g) " " deltaH^(@)lt0kJ How do the deltaE^(@)and deltaH^(@) compare for this reaction ?

Write the expression for K_p for the reaction: CaCO_3(s) hArr CaO(s) +CO_2(g)

What are the signs of DeltaH_(r)and DeltaS_(r) "for the reaction" 2C(s)+O_(2)(g)to2CO(g)

At 25^(@)C , the standard reaction enthalpy for the reaction, 2C(graphite, s) +O_(2)(g)to2CO(g) is -221.0kJ. Does this enthalpy change indicate the standard enthalpy of formation of CO(g) ? If not, then what would be the value of the enthalpy of formation of CO(g) at 25^(@)C ?

K_p/K_c for the reaction: CO(g)+1/2O_2(g) hArr CO_2(g) is :
