A chemist fills a reaction vessel with 9.20 atm nitrogen monoxide (NO) gas, 9.15 atm chlorine (CI) gas, and 7.70 atm nitrosyl chloride (NOCI) gas at a temperature of 25.0°C. Under these conditions, calculate the reaction free energy AG for the following chemical reaction: 2NO(g) +CI (8) - 2NOCI (8) Use the thermodynamic information in the ALEKS Data tab. Round your answer to the nearest kilojoule

The reactions free energy

Explanation:

From the question we are told that

      The pressure of (NO) is

      The  pressure of  (Cl) gas is  

       The  pressure of nitrosly chloride (NOCl) is

The reaction is

                 ⇆  

 From the reaction we can  mathematically evaluate the (Standard state  free energy ) as

The Standard state  free energy for NO is  constant with a value  

 The Standard state  free energy for is  constant with a value                  

 The Standard state  free energy for is  constant with a value

Now substituting this into the equation

The pressure constant is evaluated as

Substituting  values  

The free energy for this reaction is evaluated as

Where R is gas constant with a value  of  

          T is temperature in K  with a given value of  

   Substituting value

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."

girl imma just put my comment here because i need a couple point okurrttt
