In the arrhenius equation, temperature is directly proportional to which factor

What will most likely happen when two bromine atoms bond together?

What does the symbol (–hfus) indicate in a phase change?

Some liquids can be distilled, but only at temperatures that are so high that it is impractical, or so high the compound decomposes. explain why distillation such compounds at significantly less than atmospheric pressure (some degree of vacuum) would solve this problem.
