A student investigates the catalytic removal of a hypothetical dissolved contaminant, \(\text{R(aq)}\), by \(\text{H}_2\text{O}_2\text{(aq)}\). The temperature is maintained at \(298\ \text{K}\), and the same catalyst surface area is used in each trial. The student obtains the following initial-rate data.

Trial	\([\text{R}]\) \((\text{M})\)	\([\text{H}_2\text{O}_2]\) \((\text{M})\)	Initial disappearance rate of \(\text{R}\) \((\text{M}\,\text{s}^{-1})\)
\(1\)	\(0.010\)	\(0.010\)	\(5.0\times10^{-5}\)
\(2\)	\(0.040\)	\(0.010\)	\(1.0\times10^{-4}\)
\(3\)	\(0.010\)	\(0.040\)	\(4.0\times10^{-4}\)
\(4\)	\(0.040\)	\(0.040\)	\(8.0\times10^{-4}\)

Which of the following gives both the differential rate law and the units of the rate constant, \(k\), that are consistent with the data?
