Calculate amount of methane formed by liberation of 149.6 ~kJ of heat using following equation. C _ ( s ) +2 H _ 2( ~g ) CH _ 4( ~g ) H =-74.8 ~kJ / mol

Options

  1. A16 ~g
  2. B24 ~g
  3. C32 ~g
  4. D48 ~g

Correct answer

C. 32 ~g

Step-by-step solution

According to the given reaction, 74.8 ~kJ of heat is evolved when 1 mol of methane is formed. aligned & 74.8 ~kJ 1 ~mol CH ₄=16 ~g CH ₄ & 149.6 ~kJ x ~g CH ₄ & x= 149.6 16 74.8 =32 ~g aligned
