8) 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 at a particular moment, what is the rate of disappearance of C2H6O at that moment? 2 K2Cr207 + 8 H2SO4 + 3 C2H60-2 Cr2(SO4)3 + 2 K2SO4 + 3 CH3COOH + 11 H2O A) 1.09 mol/min B) 4.92 mol/min C) 2.46 mol/min D) 0. 547 mol/min 9) For a reaction that follows the general rate law, Rate = k[A][B]2, what will happen to the rate of reaction if the concentration of B is increased by a factor of 4.00? The rate will A) increase by a factor of 16.0. C) decrease by a factor of 1/4.00. B) decrease by a factor of 1/ 16.0. D) increase by a factor of 4.00.
