Consider the following reaction at 25°C for which the following data are relevant: 2NO(g) + O2(g) → 2NO2(g) ΔH° = ‐114 kJ/mol ΔS° = ‐146 J mol‐1 K‐1
a) Sketch a ΔG° versus temperature graph.
b) Over what temperature range will this reaction be spontaneous under standard conditions at constant temperature and pressure?

If a planet rotates 360 degrees during a 24 hour time period, what does that tell us about the planet? a. the middle of the planet is in darkness b. the seasons on the planet vary every day. c. the planet runs on a 12-hour time clock. d. the temperature on the planet varies daily.

Harvey kept a balloon with a volume of 348 milliliters at 25.0˚c inside a freezer for a night.  when he took it out, its new volume was 322 milliliters, but its pressure was the same.  if the final temperature of the balloon is the same as the freezer’s, what is the temperature of the freezer? the temperature of the freezer is  kelvins.
