  Ok good because I had the product choice but then X it on the answer sheet and changed it to choice 1 or 2

  Yep @Samnicole16 because a decrease in hydronium concentration means an increase in pH and vice versa

  The graph was clearly the direct relationship. As temperature increases, pressure increases in a linear fashion. It has nothing to do with an asymptote. Plus, it cannot go negative because the graph shown is only the first quadrant. You overthought the question.

  @Bennykor No that would be inverse, it went straight up.

  No! It was asking for Ideal gas, you do NOT want pressure to increase. It has to go down.

  But since it was an ideal gas shouldn't the pressure have been decreasing? @Samnicole16 @jhomatas48

  @jacobreis It is equal. It is true that one had 2 Hydrogens and the other only had one hydroxide but what they wanted you to say was that a neutral solution has equal amounts of the two ions, making a pH of 7.

  and sorry, but a linear line does not make sense

  no because they Just asked for the relationship between temperature and pressure. As temperature increases so does pressure

  As temp increase the pressure will slowly keep approaching o pressure but never full reach it
