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:

where's the diagram?

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
