The thermochemical equation representing one process used for the synthesis of ammonia involves the equilibrium shown, N2(g) + 3 H2(g) 2 NH3(g) For this reaction, DH° = -92.2 kJ, DG° = -33.4 kJ. All things considered, one concludes that Question 12 options: 1) the coefficients give us the mole ratios but not the volume ratios of the reacting species. 2) an increase in pressure favors an increase in the yield of ammonia. c. carrying out the reaction at a higher temperature shifts the position of equilibrium to the right, thus favoring an increase in the yield of ammonia. d. cooling the mixture to remove ammonia from the reaction mixture unfortunately also decreases the overall yield of ammonia. e. the mixture does not need heating, in fact, cooling the mixture assists the rapid establishment of equilibrium
The boiling point of propylamine, CH3CH2CH2NH3, is 48 °C while that for its isomer trimethylamine, (CH3)3N, is only 3 °C. Explain the difference on the basis of the intermolecular forces
Suppose 1.00 g of water (saturated liquid) evaporates isobarically at atmospheric pressure of 1.013x10^5 Pa. Its volume in the liquid state is 1.00 cm3 and its volume in the vapour state is 1671 cm3.
