variation of ∆G with temperature
What variation of ∆G with temperature means in Chemistry A-Level, as defined for AQA.
Definition of variation of ∆G with temperature
Check what you remember
Read the wording for your board, then hide it and explain variation of ∆G with temperature in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
Treat ∆G = ∆H − T∆S as a straight line of ∆G against T with intercept ∆H and gradient −∆S, so a positive ∆S makes ∆G fall as the temperature rises.
