4) 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 1.24 mol/min at a
particular moment, what is the rate of disappearance of C2H6O at that moment?
2 K2Cr2O7 + 8 H2SO4 + 3 C2H6O →2 Cr2(SO4)3 + 2 K2SO4 + 11 H2O
A) 1.86 mol/min B) 3.72 mol/min
C) 0.826 mol/min D) 0.413 mol/min
