Which of the following provide(s) a valid description relating collisions and reaction rate? Decreasing the reactant concentration will increase reaction rate because if there are fewer particles there is more room to collide. Increasing the temperature will decrease reaction rate because if the particles are moving faster there will be fewer collisions. both of the above neither of the above

Which of the following changes will increase the solubility of a gas in a liquid (like the carbonation in a beverage)? A. Decreasing the partial pressure of the gas while decreasing the temperature B. Increasing the partial pressure of the gas while decreasing the temperature C. Increasing the partial pressure of the gas while increasing the temperature D. Decreasing the partial pressure of the gas while increasing the temperature E. Gas solubility is unaffected by pressure or temperature.

Along a curve showing a linear relationship, for each increase
in x of one unit, y changes by the same amount.
I drew the curve that you can see on the right, but I'm not sure if
it's correct and from which point it should start and where it
should end.
Please, help asap.
Thank you in advance!
