What is K_c for the following equilibrium concentration of each substance is : 2SO_2(g)+O_2\rightleftharpoons2SO_3(g) ​

Question

What is
`K_c` for the following equilibrium concentration of each substance is :


`2SO_2(g)+O_2\rightleftharpoons2SO_3(g)`
​

Answer 1

As per the question ,

`2SO_2(g)+O_2\rightleftharpoons2SO_3(g)` (given)

`\: \: \: \: \: \: \: \: \: \: \: \: \: \:`

`K_c = ([SO_3]^2)/([SO_2]^2[O_2])`

`\: \: \: \: \: \: \: \: \: \: \: \: \: \:`

`\: \: \: \: \: = ( ( 1.9)^2M^2)/((0.6)^2(0.82)M^3)`

`\: \: \: \: \: \: \: \: \: \: \: \: \: \:`

`\: \: \: \: = 12.229 M^( - 1)` (approximately)

`\: \: \: \: \: \: \: \: \: \: \: \: \: \:`

Hence , K for the equilibrium is
`12.229M^(-1)`
