Lecture 19: Gibbs free energy

Question 1

What is the equation for Gibbs free energy?

Answer 1

∆𝐺 0= ∆𝐻0 − 𝑇∆𝑆0

Question 2

What is enthalpy?

Answer 2

‘enthalpy’ = (heat)

Question 3

What is entropy?

Answer 3

‘entropy’ = (chaos)

Question 4

Using gibbs energy, how can we tell if the reaction is spontaneous?

Answer 4

∆𝐺 0 < 0 = 𝑠𝑝𝑜𝑛𝑡𝑎𝑛𝑒𝑜𝑢𝑠

∆𝐺 0 > 0 = 𝑛𝑜𝑡 𝑠𝑝𝑜𝑛𝑡𝑎𝑛𝑒𝑜𝑢s
