Title: Compare Haber and contact process
Post by: tommygun999 on February 19, 2012, 05:38:44 AM
The haber process and contact process uses equilibrium principles to enable efficient production of ammonia and sulfuric acid, yet solutions arrived at are very different. Why, when both are equilibrium scenarios are their conditions similar in some ways and different in others?

Hard to understand what this question is trying to ask.  What is meant by "solutions" -- are the equilibria "solved" in some way?  The question can't possibly mean "solutions" as why do we get ammonia out of one and sulfuric out of the other, right?

It's the more curious for the fact that both equilibria would demonstrate the same response to both temperature and pressure. That is, a shift towards the products for increased pressure and a shift towards the reactants for increased temperature (since the forward reactions of both are exothermic). But the two reactions don't feature a single element in common so that's a fairly considerable difference on which to focus.
