Calculations for Gibbs free energy

Postby Brevin Hensley 1C » Sat Feb 23, 2019 11:38 pm

I understand how to solve the equation . But for other methods when given the number of moles can someone explain how to solve these/what is the reasoning behind it? Thank you.

When given the number of moles and asked to find delta G, you can use the moles when finding entropy by subtracting the number of moles of reactants from the products.

Remember that although you are using delta G= delta H-T times delta S, you can still replace components of the equation with other equations you learned previously. So, you could find an equation for delta H that includes moles and any other given information. Then you could substitute this value with your delta H and proceed.
