Given that C _ ( g ) +4 H _ ( g ) CH _ 4( ~g ) H ^ =-1665 ~kJ What is bond energy per mole of C - H bond ?

Options

  1. A416 ~kJ ~mol ⁻¹
  2. B-416 ~kJ ~mol ⁻¹
  3. C832.5 ~kJ ~mol ⁻¹
  4. D-832.5 ~kJ ~mol ⁻¹

Correct answer

A. 416 ~kJ ~mol ⁻¹

Step-by-step solution

In the given reaction, there are 4 C - H bonds formed per mole of CH ₄ . Bond energy per mole of aligned fCH ₄ & = -(-1665 ~kJ ) 4 & =416.25 ~kJ aligned
