Consider the reaction: N ₂+3 H ₂ 2 NH ₃ carried out at constant temperature and pressure. If H and U are the enthalpy and internal energy changes for the reaction, which of the following expressions is true?

Options

  1. AH =0
  2. BH = U
  3. CH < U
  4. DH > U

Correct answer

C. H < U

Step-by-step solution

aligned & H = U + nRT & n =-2 & H = U -2 RT & H < U aligned
