A) Rate of an exothermic reaction increases with temperature
B) Solubility of NaOH increases with temperature
C) \[{{K}_{p}}\]for \[{{N}_{2}}(g)+3{{H}_{2}}(g)2N{{H}_{3}}(g)\]increases with increase in pressure
D) For gaseous reaction \[2\,B\xrightarrow{{}}A\,;{{K}_{p}}\] is smaller than \[{{K}_{e}}\]
Correct Answer: A
Solution :
Statements [a] and [c] are incorrect. The correct statements are [a] Exothermic reactions are favoured by Low temperature whereas endothermic reactions are favoured by high temperature. [c] \[\because \] \[{{K}_{p}}={{K}_{c}}{{(RT)}^{\Delta n}}\] \[\therefore \,\,{{K}_{p}}\] is a function of temperature and stoichiometric coefficient only, not of pressure.
