Will this entropy change by positive or negative N2 (g) 3h2 (g) 2nh3 (g)?

Positive


What is true for the gas phase reaction shown below 2NH3 gives n2 plus 3h2 delta H equals 160.58 kj?

s is positive and g is negative at low temperatures only


Which of the following reactions would result in decreased entropy A PCl5 g PCl2 g plus Cl2 g B 2CH4 g plus 3O2 g 2CO g plus 4H2O g C N2 g plus 3H2 g 2NH3 g D MgCl2 s Mg2 plus aq plus 2Cl aq-?

The reaction that would result in decreased entropy is N2 + 3H2 → 2NH3.

What does the 2 in 2NH3 mean?

The coefficient (in this case a 2) indicates the number of moles or molecules of the compound. So, 2NH3 means there are 2 moles or 2 molecules of ammonia (NH3).
