  • a)
    14.31 KJ
  • b)
    57.23 KJ
  • c)
    48.14 KJ
  • d)
    66.31 KJ
Correct answer is option 'C'. Can you explain this answer?

A/Q molar ratio of C2H4 and CH3CHO is 8:1
So from eqn 1
∆H = 8 45.54
= 364.32 kJ
Similarly from eqn 
∆H = 68.91 1 
= 68.91 kJ
Total ∆H = 364.32+68.91
Therefore, enthalpy change per mole of C2H5OH used 364.32+68.91/9
= 48.14 kJ
