A large sport utility vehicle has a mass of 2.5 * 103 kg. Calculate the mass of CO2 emitted into the atmosphere upon accelerating the SUV from 0.0 mph to 65.0 mph. Assume that the required energy comes from the combustion of octane with 30% efficiency. (Hint: Use KE = 1/2 mv2 to calculate the kineticenergy required for the acceleration.)
The citizens of the world burn the fossil fuel equivalent of 7 * 1012 kg of petroleum per year. Assume that all of this petroleum is in the form of octane (C8H18) and calculate how much CO2 (in kg) the world produces from fossil fuel combustion per year. (Hint: Begin by writing a balanced equation for the combustion of octane.) If the atmosphere currently contains approximately3 * 1015 kg of CO2, how long will it take for the world’s fossil fuel combustion to double the amount of atmospheric carbon dioxide?
Part 1
A student carried out an investigation to observe the effect of changing
concentration of sulfuric acid on the breakdown of calcium carbonate
(marble) chips. They changed the concentration of the acid between
each test but kept the size of the marble chips constant. The full equation
for the reaction and a graph of the overall results can be seen below.
CaCO3(s) + H₂SO4(aq) → CaSO4(aq) + CO2(g) + H₂O (1)

b)
Rate of Reaction

Concentration of Acid (mol dm³)
Explain, using collision theory, why the student obtained
these results, and state what they could conclude about the
effect of changing concentration of acid on the rate of reaction
between calcium carbonate and sulfuric acid.
If the student had ground up the calcium carbonate chips into
a powder and run the tests again, what would you expect to
happen to the rate of reaction? Briefly explain why by
applying collision theory.
Part 2
The student ran the same experiment, but this time changed the
temperature, increasing it…
