For the reaction, C ₂ H ₂ OH (l)+30_ 2( ~g ) 2 C ₂ O (l) U is the heat of reaction at constant volume. Then heat of reaction at constant pressure is

Options

  1. AH = U + RT
  2. BH = U +2 RT
  3. CH = U -2 RT
  4. DH = U - RT

Correct answer

D. H = U - RT

Step-by-step solution

aligned & H= U+(2-3) R T & H= U-R T aligned
