Which of the following lines correctly show the temperature dependence of equilibrium constant K , for an exothermic reaction?

Options

  1. AA   &   D
  2. BA   &   B
  3. CB   &   C
  4. DC   &   D

Correct answer

B. A   &   B

Step-by-step solution

The Arrhenius equation in Logarithmic form: In   K = - ∆ H RT + ln   A On comparing with y = mx + c ,   m = - ∆ H R and c = ln   A . For an exothermic reaction, the value of ∆ H < 0 , slope will be positive and the intercept can be either positive or negative.
