A roller coaster starts from rest at the top of the first hill, and glides freely.
2. Describe how the energy in the car is transformed continually as
it glides along the track
3.Explain the state of energy in the roller coaster car at the top of
the first hill, mid-way down the first hill, at the bottom of the
first hill and mid-way up the second hill.

For the reaction, 4 a(g) + 3 b(g) => 2 c(g), the following data were obtained at constant temperature. experiment initial[a],mol/l initial [b],mol/l initial rate,m/min 1 0.200 0.150 5.00 2 0.400 0.150 10.0 3 0.200 0.300 10.0 4 0.400 0.300 20.0 which of the following is the correct rate law for the reaction? 1. rate = k[a]2[b]2 2. rate = k[a][b] 3. rate = k[a]2[b] 4. rate = k[a][b]2
