Areaction mixture that consisted of 0.35 molh2and 1.6 mol i2 was introduced into a 2 l flask and heated. at the equilibrium, 60% of the hydrogen gas had reacted. what is the equilibrium constant kc for the reactionh2(g) + i2(g)⇀↽2 hi(g)at this temperature?

The equilibrium constant Kc for the reaction is :

16.07

Explanation:

The balanced equation is :

First ,

"At the equilibrium, 60% of the hydrogen gas had reacted"

This means the degree of dissociation = 60% = 0.6

Here we are denoting degree of dissociation by ="x" =  0.6

Now , consider the equation again,

H2                       I2                 2HI

0.35                   1.6                0            (Initial Concentration)

0.35(1 - x)           1.6(1 - x)         2x    (At equilibrium)

0.35(1 - 0.6)       1.6(1 - 0.6)      2(0.6)

0.14                     0.64                 1.2

calculate the concentration of each:

The equilibrium constant for this reaction "Kc" can be written as:

its going to be mutualism cuz they both benefit from the relationship.
