JEE Main 2021 — Chemical Equilibrium Question with Solution
From: JEE Main 2021 (Online) 27th August Evening Shift
Question
When 5.1 g of solid NH4HS is introduced into a two litre evacuated flask at 27C, 20% of the solid decomposes into gaseous ammonia and hydrogen sulphide. The Kp for the reaction at 27C is x 102. The value of x is _____________. (Integer answer) [Given R = 0.082 L atm K1 mol]

Correct answer
6
Step-by-step explanation
moles of NH4HS initially taken = = 0.1 mol
volume of vessel = 2 litre
partial pressure of each component
= 0.246 atm
kP = P P = (0.246)2 = 0.060516
= 6.05 102
x = 6
volume of vessel = 2 litre
partial pressure of each component
= 0.246 atm
kP = P P = (0.246)2 = 0.060516
= 6.05 102
x = 6
