Answer:
A. 1
Explanation:
The higher you get in the atmosphere the cooler the temperature will be. The reason it's actually colder is because, as you go up in the atmosphere, the Earth's atmosphere feels less pressure the higher up you go. So as the gas in the atmosphere rises it feels less pressure, which makes it expand.
Hope this Help :)

The industrial synthesis of ammonia is spontaneous.
to to prove this one calculate the gibbs free energy(delta G)
= delta G = Delta H -T delta s
delta H = -92.2 kj in joules -92.2 x1000 =-92200j
delta s = -199j/k
T= 25+273= 298k
delta G is therefore= -92200-298(-199)=-32898j
since delta G is negative the reaction is therefore spontaneous
