4short Q&A pairs drawn directly from our worked dot-point answer. For full context and worked exam questions, read the parent dot-point page.
What is feasible but slow?Show answer
A positive EMF means the reaction can happen, not that it does so quickly; kinetic factors can make a feasible reaction immeasurably slow.
What are non-standard conditions?Show answer
Changing concentration shifts the electrode potential (by Le Chatelier on the half-equation), so predictions from standard values may fail when conditions are far from standard.
What is q1?Show answer
Define the standard electrode potential of a half-cell. [2 marks]
What is q2?Show answer
Using () and (), calculate the EMF of a cell made from these half-cells. [1 mark]
