Predict whether each of the following reactions would be spontaneous or non spontaneous under standard conditions or if it is impossible to tell with the data given. a)2KClO3(s)+3C(s)-->3CO2(g)+2KCl(s) Exothermic b) 2NO(g) + O2(g) ---> 2NO2(g) Exothermic...

Whats the difference between sinx and sin^2(x) and how do you get rid of sin^2(x) to make it like sinx

In the problem it states if the reactions underwent standard conditions, would that mean they would all have the same temperature and delta s meaning the only thing that would ,make the difference is the delta H?
