Options

  1. ASuspended inside a closed box maintained at 57^ ^ ^ C , a spherical ball with a surface area of 20 cm^2 absorbs all
  2. BSuspended inside a closed box maintained at 57^ ^ ^ C , a spherical ball with a surface area of 20 cm^2 absorbs all
  3. CSuspended inside a closed box maintained at 57^ ^ ^ C , a spherical ball with a surface area of 20 cm^2 absorbs all
  4. DSuspended inside a closed box maintained at 57^ ^ ^ C , a spherical ball with a surface area of 20 cm^2 absorbs all

Correct answer

C. Suspended inside a closed box maintained at 57^ ^ ^ C , a spherical ball with a surface area of 20 cm^2 absorbs all

Step-by-step solution

The Arrhenius equation is given as k=Ae−EaRT∴ln⁡k=ln⁡A−EaRT\begin{aligned} & k=A e^{-\frac{E_a}{R T}} \\ & \therefore \quad \ln k=\ln A-\frac{E_a}{R T} \end{aligned} In kv/s1 T\mathrm{k} v / \mathrm{s} \frac{1}{\mathrm{~T}} gives a straight line graph with slope =−EaR=-\frac{E_{\mathrm{a}}}{R} and intercept =ln⁡A=\ln \mathrm{A} Which plot of k vs 1 ~T is consistent with Arrhenius equation?
