6. Consider a solution made from a nonvolatile solute and a volatile solvent. Which of the statement is true? a) The vapor pressure of the solution is always greater than the vapor pressure of the pure solvent. b) The boiling point of the solution is always greater than the boiling point of the pure solvent. c) The freezing point of the solution is always greater than the freezing point of the pure solvent. d) None of the above

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.

im not exactly sure but i think its b!
