What is the standard enthalpy of formation of nh3 gas?
1 answer(s)
I just learned this in my chemistry class. The standard enthalpy of formation for ammonia gas, which is NH3, is -46.1 kJ/mol. That negative sign is very important. It means that heat is released when you make it. So the reaction gets warm. This is called an exothermic reaction. It is a number you see a lot in homework problems. I hope this answer is a help for you.
