Problem

Hydrogen peroxide decomposes according to 2H₂O₂(aq) → 2H₂O(l) + O₂(g). If O₂ forms at 1.6 mmol·min⁻¹, what is the rate of disappearance of H₂O₂ expressed in mol·s⁻¹? a) 1.6×10−3  mol⋅s−11.6 \times 10^{-3}\;\text{mol}\cdot\text{s}^{-1} b) 5.3×10−5  mol⋅s−15.3 \times 10^{-5}\;\text{mol}\cdot\text{s}^{-1} c) 2.7×10−5  mol⋅s−12.7 \times 10^{-5}\;\text{mol}\cdot\text{s}^{-1} d) 8.0×10−6  mol⋅s−18.0 \times 10^{-6}\;\text{mol}\cdot\text{s}^{-1}
