JEE Main 2019 — Chemical Equilibrium Question with Solution

JEE Main 2019 (08 Apr Shift 2)

Question

For the following reaction, equilibrium constant are given:

Ss+O2g⇌SO2g; K1=1052

2Ss+3O2g⇌2SO3g; K2=10129

The equilibrium constant for the reaction, 2SO2g+O2g⇌2SO3g is:

Choose an option

Correct answer
B1025

Step-by-step explanation

Ss+O2g⇌SO2g; k1=1052 ……(i)

2Ss+3O2g⇌SO2g; k2=10129 ……(ii)

2SO2g+O2g⇌2SO3g; keq=?

keq=SO32SO22O2

k1=SO2O2=1052

k2=SO32O23=10129

keq=k2k12=1012910522=1025
