For a reaction, A + B 2 + ⟶ B + A 2 + , at 25 0 C E 0 = 0 . 2955 V . The value of K eq is

Options

  1. A10
  2. B10 10
  3. C- 10
  4. D10 - 10

Correct answer

B. 10 10

Step-by-step solution

Given that, For a reaction, A + B 2 + ⟶ B + A 2 + , E ° = 0 . 2955 V T = 25 ° C ,   ⇒ T = 298   K   n = 2 Using Nernst equation, E ° = 2 . 303 RT nF logk eq E ° = 0 . 0591 n logk e q at   25 o C ⇒    0 . 2955 = 0 . 0591 2 log k eq k eq = 10 10 Therefore, the value of K eq   is 10 10 .
