Gibbs Free Energy Homework: CaCO3 <-> CaO + CO2
Homework Statement CaCO3 <-> CaO + CO2 At 900K, equilibrium pressure of CO2 is 0.0423 atm. Calculate Gibbs Free energy of Reaction and K.Homework Equations delta G = -RTlnKThe Attempt at a Solution delta G = 5656.3 cal/mol K = 0.0423 I have a feeling that this is incorrect Could someone...- jin.cao

Forgotten Fractions? Get Guidance Here!
did factor out the 3 it becomes 27, i think and canceled some of the 4-2x , as you suggested but the main problem for me is still so much x, cant really isolate it, because i tried expanding it and i get like x^1 , x^2, x^3, X^4... and do not know how to solve those- jin.cao

Balancing Chemical Reactions: Isobutyric Acid + 2-Methoxyethanol
no, because i am suppose to make procedure to create the product so i will have to change the condition to shift equilibrium to the right side i guess... why? -
