Hi everyone here we have a question asking what is the free energy change for the reaction at equilibrium? When the temperature equals 25 degrees Celsius three flooring gasses plus roaming gashes forms to roaming fluoride gasses and our constant is 2.47 times 10 to the 80th. So we need to recall that if our energy change is less than zero, the reaction is spontaneous. If our change in energy equals, zero the reaction is at equilibrium. If our change in energy is greater than zero, the reaction is non spontaneous. So for this reaction to be at equilibrium are changing energy has to equal zero. So our change in energy equals zero. And that is our final answer. Thank you for watching. Bye.
