|-
| |
| | Next, we will define the '''Equilibrium Reaction.'''

|-
| | '''Tools >> Reaction Manager'''

Point to '''Chemical Reactions Manager'''
| | Under '''Tools''', click on '''Reactions Manager.'''

'''Chemical Reactions Manager''' window opens.

|-
| | '''Chemical Reactions >> Add Reaction'''
| | Under '''Chemical Reactions''' tab, click on the green coloured '''Add Reaction''' button.

|-

|-
| | '''Description >> Reaction of carbon monoxide and water vapor to form carbon dioxide and hydrogen'''
| | Let’s enter the '''Description.'''

“'''Reaction of carbon monoxide and water vapor to form carbon dioxide and hydrogen.”'''

|-
| | Point to '''Components/Stoichiometry'''
| | Next part is the table of '''Components/Stoichiometry.'''

|-
| | Point to '''Name''' field

| | First is '''Gibbs Energy of Reaction.'''

If the '''equilibrium constant''' is unknown, it is calculated directly from '''Gibbs energy of reaction'''.

|-
| | Point to '''T function'''

Here the '''equilibrium constant''' can be defined as a function of temperature.

It is in the form of '''ln Keq = f(T).'''

|-

| | Third is '''Constant value''' where the equilibrium constant is defined directly.

|-
| | Select '''Gibbs Energy of Reaction'''
| | Here, we don't know the '''equilibrium constant '''directly or as a function of temperature.

So, we will let it calculate from the '''Gibbs energy of reaction'''.

Select '''Gibbs Energy of Reaction.'''

|-
| | At the bottom, Click on '''OK.'''

Close '''Chemical Reactions Manager''' window.
| | Click on '''OK''' at the bottom.

| |
| | Now let’s insert two more '''material streams''' that exit the '''Equilibrium Reactor.'''

|-
| | Click and Drag '''Material Stream '''to the flowsheet
| | To do that, let us drag one '''Material Stream '''to the '''flowsheet'''.

|-
| |
| | Let us now arrange it.

|-
| | Point to the stream.
| | We will leave that '''stream''' as unspecified.

|-
| | Type '''Vapour Product'''
| | Then we will change the name of this '''stream '''to '''Vapour Product.'''

|-
| | Click and drag '''Material Stream '''to the '''flowsheet'''
| | Next, we will insert another '''Material Stream.'''

|-
| |
| | Let us once again arrange it.

|-
| | Point to the stream.
| | Leave that '''stream''' as unspecified.

|-
| | Type '''Liquid Product'''
| | And name this '''stream '''as '''Liquid Product.'''

|-
| | Click and drag '''Energy Stream''' to the flowsheet
| | Next, we will insert one '''Energy Stream.'''

|-
