Consider the sublimation of iodine at 25.0 °C : I2(s) → I2( g) c. Explain why iodine spontaneously sublimes in open air at 25.0 °C
Consider the evaporation of methanol at 25.0 °C : CH3OH(l) → CH3OH(g) a. Find ΔG° r at 25.0 °C.
Consider the evaporation of methanol at 25.0 °C : CH3OH(l) → CH3OH(g) b. Find ΔG r at 25.0 °C under the following nonstandard conditions: i. PCH3OH = 150.0 mmHg ii. PCH3OH = 100.0 mmHg iii. PCH3OH = 10.0 mmHg
Consider the reaction: CO2( g) + CCl4( g) ⇌ 2 COCl2( g) Calculate ΔG for this reaction at 25 °C under the following conditions: i. PCO2 = 0.112 atm ii. PCCl4 = 0.174 atm iii. PCOCl2 = 0.744 atm
Use data from Appendix IIB to calculate the equilibrium constants at 25 °C for each reaction. a. 2 CO( g) + O2( g) ⇌ 2 CO2( g)
Use data from Appendix IIB to calculate the equilibrium constants at 25 °C for each reaction. b. 2 H2S(g) ⇌ 2 H2(g) + S2(g)
