Question 1
For a particular chemical reaction ΔH = 4.5 kJ and ΔS = –23 J/K. Under what temperature condition is the reaction spontaneous?
◦
When T< –196 K.◦
When T< 196 K.◦
The reaction is spontaneous at all temperatures.◦
The reaction is not spontaneous at any temperature.◦
When T> 196 K.Question 2
For a particular reaction the equilibrium constant is 0.0110 at 370.°C and ΔH° is +16.0 kJ at 25°C. Assuming ΔH° and ΔS° are temperature independent, calculate ΔS° for the reaction.
◦
5.75 J/K◦
–5.75 J/K◦
–12.6 J/K◦
12.6 J/K◦
None of these are correct.
