MCQ
Given reaction is $2{X_{(gas)}} + {Y_{(gas)}}$ $\rightleftharpoons$ $2{Z_{(gas)}} + 80\,kcal$ Which combination of pressure and temperature gives the highest yield of $Z$ at equilibrium
  • A
    $1000$ $atm$ and ${500\,^o}C$
  • B
    $500$ $atm$ and ${500\,^o}C$
  • ✓
    $1000$ $atm$ and ${100\,^o}C$
  • D
    $500$ $atm$ and ${100\,^o}C$
✓

Answer

Correct option: C.
$1000$ $atm$ and ${100\,^o}C$
(c) The reaction takes place with a reduction in number of moles (volume) and is exothermic. So high pressure and low temperature with favour the reaction in forward direction
