Question

Which of the following rate laws has an overall order of 0.5 for reaction involving substances $x,y$ and $z$ ?

• A. Rate $=k\left[C_x\right]\left[C_y\right]\left[C_z\right]$
• B. Rate $=k{\left[C_x\right]}^{0.5}{\left[C_y\right]}^{0.5}{\left[C_z\right]}^{0.5}$
• C. Rate $=k{\left[C_x\right]}^{1.5}{\left[C_y\right]}^{-1}{\left[C_z\right]}^0$
• D. Rate $=k\left[C_x\right]{\left[C_z\right]}^2/{\left[C_y\right]}^2$

Answer 1

Answer: (C)

Order of reaction $=1.5-1+0=0.5$
