How do we predict the conditions (high temperature, low temperature, all temperatures, or no temperatures) under which each of the following reactions will be spontaneous.
(I have the correct answers to the following so I really want to understand how to solve this question or approach it - Thank you)
a) H2O(g) -->H2O(l)
b) CO2(s)-->CO2(g)
c) H2(g)-->2H(g)
d) 2NO2(g)-->2NO(g)+O2(g)(endothermic)
*Please expain how to determine the answers - I have the correct solutions*
