Equilibrium Question 682
Question: Given reaction is $ 2{X_{(gas)}}+{Y_{(gas)}} $ ⇌ $ 2{Z_{(gas)}}+80,kcal $ Which combination of pressure and temperature gives the highest yield of Z at equilibrium [NCERT 1979]
Options:
A) 1000 atm and $ 500^{o}C $
B) 500 atm and $ 500^{o}C $
C) 1000 atm and $ 100^{o}C $
D) 500 atm and $ 100^{o}C $
Show Answer
Answer:
Correct Answer: C
Solution:
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
