Be sure to answer all parts. Consider the reaction N2(g) + 3H2(g) → 2NH3(g)ΔH o rxn = −92.6 kJ/mol If 3.0 moles of N2 react with
9.0 moles of H2 to form NH3, calculate the work done (in joules) against a pressure of 1.0 atm at 25°C. w = 15,000 J What is ΔU for this reaction? Assume the reaction goes to completion. ΔU = -240 kJ

Answer:
Explanation:
We have the reactions:
A:
B:
Our <u>target reaction</u> is:
We have as a reactive in the target reaction and
is present in A reaction but in the products side. So we have to<u> flip reaction A</u>.
A:
Then if we add reactions A and B we can obtain the target reaction, so:
A:
B:
For the <u>final Kc value</u>, we have to keep in mind that when we have to <u>add chemical reactions</u> the total Kc value would be the <u>multiplication</u> of the Kc values in the previous reactions.
