本题目来源于试卷: How Much How Fast & How Far E.2 Rate of Chemical Change，类别为 IB化学
[单选题]
If the rate expression for a reaction 2 X+Y→Zis rate = $\kappa$$[X]^2$, which of the following is most likely ture about"Rate determining step"or"Molecularity"?
A. 2X+Y 3
B. X+Y 1
C. X+X 2
D. XY+X 2
参考答案: C
本题详细解析:
C The molecularity is given by the power to which the species is raised to in the rate expression. X is raised to the power of two meaning the rate determining step involves two X molecules.
