The formula for the decomposition for ammonia would be 2NH3 --> N2 + 3H2

2NH3 + 2NA = 3H2 + NA3N2

The formula for the synthesis of ammonia from diatomic nitrogen and hydrogen is: N2+3H2-->2NH3

-46 kj/mol

2 X 3 = 6.

s is positive and g is negative at low temperatures only

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

The formula for the decomposition for ammonia would be 2NH3 --> N2 + 3H2

n2(g)+3H2(g)>2NH3(g)

2NH3 + 2NA = 3H2 + NA3N2

An example of a reaction that would result in decreased entropy is a dehydration reaction.

N2 + 3H2 --> 2NH3 N2 + 3H2 --> 2NH3

the haber process the haber process the equation is N2 + 3H2 <--> 2NH3 the haber process! its easy, the equation is N2 + 3H2 <--> 2NH3

the haber process the haber process the equation is N2 + 3H2 <--> 2NH3 the haber process! its easy, the equation is N2 + 3H2 <--> 2NH3

N2 + 3h2

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).
