11th Class Chemistry Thermodynamics

  • question_answer 31) For the reaction, \[2Cl(g)\to C{{l}_{2}}(g);\]what are the signs of \[\Delta H\] and \[\Delta S\]?  

    Answer:

    (i) Bond formation is exo-energic process hence \[\Delta H=-ve.\] (ii) Number of particles are reduced hence entropy will decrease, i.e.,\[\Delta S=-ve.\]
