Question
Dichromate ion is reduced by chloride ion according to the equation below. If [Cl–] is decreasing at a rate of 0.37 mol L-1 min-1, how is the concentration of Cr3+(aq) changing?
14 H+(aq) + Cr2O7 2-(aq) + 6 Cl–(aq) → 2 Cr3+(aq) + 3 Cl2(aq) + 7 H2O(l)
A.✓ Correct
Increasing by 0.12 mol L-1 min-1
B.
Increasing by 1.11 mol L-1 min-1
C.
Decreasing by 0.12 mol L-1 min-1
D.
Decreasing by 1.11 mol L-1 min-1
