##### Calorimeter Question
« on: November 29, 2004, 07:57:50 PM »
Hi,

One mole of nitrogen and one mole of hydrogen are reacted together in a calorimeter oh heat capcity 20kJ/K. (Look carefully at these units) Calculate the change in temperature which the calorimeter will undergo.

I was thinking this was a limiting reageant question and set up the equation

N2(g) + 3H2(g) --> 2NH3(g)

But the only problem is the question said we started off with one mole of each.

Thanks

deduce which reactant is the limited reagent.

I know-I know
Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex
