5.3 Concentration Changes Over Time
IntermediateMCQMathematicalConceptual22.3k
A student investigates the kinetics of decomposition for two compounds, \(\text{X(aq)}\) and \(\text{Y(aq)}\), in separate reaction vessels at \(298 \text{ K}\). The concentration of each reactant is measured at equal time intervals of \(30 \text{ s}\), as recorded in the table below.

Time (\(\text{s}\))\([\text{X}]\) (\(\text{M}\))\([\text{Y}]\) (\(\text{M}\))
\(0\)\(0.80\)\(0.80\)
\(30\)\(0.60\)\(0.40\)
\(60\)\(0.40\)\(0.20\)
\(90\)\(0.20\)\(0.10\)

Based on the data in the table, which of the following statements correctly identifies the reaction order with respect to each reactant and provides the correct reasoning?
