The `(Co, CO_(2))` line on the Ellingham diagram slopes upwards. Give reason.

The (C,CO) line on the Ellingham diagram slopes downwards. Give reason.

Explain why in the Ellingham diagram, the (C,CO_(2)) line is nearly horizontal, but the (C,CO) line slopes downwards.

At ordinary temperature, why can CO_(2) but not O_(2) gas be liquefied by applying pressure? Give reason.

What is co-polymer? Give example.

Prove that the image of point P(costheta, sin theta) in the line having slope tan(alpha//2) and passing through origin is Q(cos(alpha-theta),sin(alpha-theta)) .

Predict the temperature for the carbon reduction of Cu_(2)O from the Ellingham diagram.

One of the reaction that takes place in producing steel from iron ore is the reduction of iron (II) oxide by carbon monoxide to give iron metal and CO_(2) . FeO(s)+CO(g)hArr Fe(s)+CO_(2)(g),K_(p)=0.265atm at 1050K. What are the equilibrium partial pressures of CO and CO_(2) at 1050K if the initial partial pressures are: p_(CO)=1.4 atm & p_(CO_(2))=0.80 atm?
