Problem

Experimental studies on the decomposition of compound X give a rate constant with units M−2 s−1M^{-2}\,\text{s}^{-1}. Four possible rate laws are proposed. Which rate law is consistent with the observed units? a) rate=k[X]\text{rate}=k[\text{X}] b) rate=k[X]2\text{rate}=k[\text{X}]^2 c) rate=k[X]3\text{rate}=k[\text{X}]^3 d) rate=k[X]1/2\text{rate}=k[\text{X}]^{1/2}
