Predicting Redox Reactions and Spontaneity
Use standard electrode potentials to predict the direction, feasibility, and spontaneity of redox reactions and identify oxidizing/reducing agents.
Why this shows up in the exam
You will be asked to predict which reactions occur spontaneously and identify the strongest oxidizing or reducing agents.
How NEET tests this
Practise it
These are real questions from past NEET papers that test this exact idea.
A solution of potassium bromide is treated with each of the following. Which one would liberate bromine?
Push further
More challenging8 harder questions built from the past papers above — a step up in difficulty, with distractors designed so you can't get there by elimination. Written and checked by our reviewers, not from a real paper.
You are given the following standard reduction potentials: Zn²⁺ + 2e⁻ → Zn; E° = -0.76 V Ni²⁺ + 2e⁻ → Ni; E° = -0.25 V If a galvanic cell is constructed using these two half-cells, what is the standard cell potential (E°cell) and which metal acts as the anode?
