Calculate the value of K p for the equation C ( s ) + CO 2 ( g ) − ⇀ ↽ − 2 CO ( g ) K p = ? given that at a certain temperature C ( s ) + 2 H 2 O ( g ) − ⇀ ↽ − CO 2 ( g ) + 2 H 2 ( g ) K p 1 = 3.09 a t m H 2 ( g ) + CO 2 ( g ) − ⇀ ↽ − H 2 O ( g ) + CO ( g ) K p 2 = 0.793

The value of for the net reaction is 1.94

Explanation:

The given chemical equations follows:

Equation 1:  

Equation 2:  

The net equation follows:

As, the net reaction is the result of the addition of first equation and the twice of second equation. So, the equilibrium constant for the net reaction will be the multiplication of first equilibrium constant and the square of second equilibrium constant.

The value of equilibrium constant for net reaction is:

We are given:

Putting values in above equation, we get:

Hence, the value of for the net reaction is 1.94

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.

the answer is c
