Question 1

The reaction has the rate law Rate = k[A][B]². Which will cause the rate to increase the most?
◦ doubling [A]
◦ lowering temperature
◦ tripling [B]
◦ quadrupling [A]
◦ doubling [B]

Question 2

The reaction that occurs in a Breathalyzer, a device used to determine the alcohol level in a person's bloodstream, is given below. If the rate of appearance of Cr₂(SO₄)₃ is 1.64 mol min^-1 at a particular moment, what is the rate of disappearance of C₂H₆O at that moment?

2 K₂Cr₂O₇(aq) + 8 H₂SO₄(aq) + 3 C₂H₆O(aq) → 2 Cr₂(SO₄)₃(aq) + 2 K₂SO₄(aq) + 11 H₂O(l)

◦ 0.547 mol min^-1
◦ 1.09 mol min^-1
◦ 2.46 mol min^-1
◦ 4.92 mol min^-1
