What is the percentage decomposition of H 2 S , if 1 mole of H 2 S is introduced into a 1.1 litre vessel at 1000 K? K C for the reaction 2 H 2 S ( g ) ⇌ 2 H 2 ( g ) + S 2 ( g ) is 1 × 1 0 - 6

Options

  1. A1.3%
  2. B0.13%
  3. C13%
  4. DNone of these

Correct answer

A. 1.3%

Step-by-step solution

K C = x 2 × 1.1 2 x 2 × 1.1 1 - x 1.1 2 1 × 1 0 - 6 = x 3 2.2 So, x = 1.3 × 1 0 - 2 = 1.3 % .
