By considering Arrhenius equation, the graph between '1/T' and 'log K', which of the following graph represents the relationship between log K and 1/T?
Correct answer: B. Option B
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
The original Arrhenius equation is: k = Ae(-Ea/RT) Which can be rewritten as: log k = -Ea/RT log Ae, where Ea log Ae/R is a constant and T is a variable. The slope of the Arrhenius equation is used to calculate activation energy. Arrhenius equation is rearranged it is a linear equation with the form y = mx + b y is log(k), x is 1/T, and m is -Ea/R .

About Reaction Kinetics
Reaction kinetics relates reaction rate to concentration, temperature, surface area and catalysts. Questions cover rate laws, reaction order, rate constants, activation energy and the activated complex, including how a catalyst lowers the activation energy without changing the overall energy change or equilibrium position.
