23.5 predictions from electrode potentials

Question 1

how can you predict feasibility of a redox reaction?

Answer 1

using standard electrode potentials

Question 2

what does the redox system of the oxidising agent have to have in order for the reaction to occur?

Answer 2

more positive standard electrode potential than the redox system of the reducing agent

Question 3

the redox system with the more positive E value…

Answer 3

will react from left to right and gain electrons

Question 4

the redox system with the less positive E value…

Answer 4

will react from right to left and lose electrons

Question 5

limitations of predictions using E values

Answer 5

reaction rate- large activation energy = no reaction
non-standard conditions
