Look at the image below. What structure is shown?  

A certain reaction has an activation energy of 25.0 kJ/mol. At what temperature will the reaction proceed four times faster than it did at 375 K?

The vapor pressure of a liquid is 47.1 kPa at 501 K and 10.5 kPa at 489 K. What is the enthalpy of vaporization of the liquid ?

For a certain reaction at 330 K, ∆Hsys = -9.9 kJ and ∆Ssys = -85 J/K, calculate ∆Suniv.

Consider a reaction that has a negative ΔH and a positive ΔS. Which of the following statements is true?  

At 298 K , ∆H = 179.2 kJ and ∆S = 160.2 J/K for the reaction shown below. CaCO3(s)  ⟶ CaO(s) + CO2(g) (a) Use the data to decide if this reaction is spontaneous at 298 K. (b) What is the temperature above which the reaction is spontaneous?

For a certain reaction at 330 K, ∆Hsys = 9.9 kJ and ∆Ssys = 85 J/K, calculate ∆Suniv.
