The following reaction is carried out on an industrial scale for the production of thionyl chloride, a chemical used in the manufacture of pesticides.
SO3(g) + SCl2(l) OSCl2(l) + SO2(g)

The thermodynamic data listed below are for 298 K. Determine the temperature at which Keq = 1.0 10^15 for the reaction.

delta Hf(kJ/mol): .....S, J/mol*K
SCl2(l): -50.......150
OSCl2(l): -250 ....120

In the following question, the answer is a
http://tinyurl.com/2musg7

My understanding is,
amount of work done of conservative force
=amount of decrease of potential energy
=amount of increase in kinetic energy

decreases of word done of nonconservative force
=decreases of mechanical energy of the entire system

Am I correct?

Why is it that as the minimum temperature is approached, the further extraction of energy becomes more and more difficult?

These are the values:

0 | 1 | 2 | 3 | 4 | 5 | 6 |
4 | 6 | 7 | 7.5 | 7.75 | 7.875 | 7.9375 |

(Excuse my crappy table making skills!)

The top row is X and the bottom is Y, the pattern will continue. I think the equation will be an exponential one but I am unsure.

Thank you for your help.
