For the reaction C ₃ H ₈(g)+5 O ₂(g) 3 CO ₂( ~g )+4 H ₂ O (l) at constant temperature, H - E is:

Options

  1. A+RT
  2. B-3 RT
  3. C+3 RT
  4. D-RT

Correct answer

B. -3 RT

Step-by-step solution

aligned C ₃ H _ 8(g) +50_ 2(g) & 3 CO _ 2( ~g ) +4 H ₂ O _ (i) n & =3-6=-3 H & = E + P V aligned or H - E = P V H - E = nRT =-3 RT
