Hypothesis 1: If you increase the temperature of a reaction, then the reaction
rate will increase because particles experience
more collisions at higher temperatures.

To test the first hypothesis, you measured the
reaction rate for several different?

volumes.
temperatures.
densities.
particle sires.

Calculate the change in entropy if br2(l) is converted to br2(g). s° for br2(l) = 152.2 j/(mol•k) s° for br2(g) = 245.5 j/(mol•k) s° for br(g) = 175.0 j/(mol•k)
