1.	Measurements show that the cell potential is affected by a number of factors such as (i) the nature of the substance that makes up each half-cell (ii) the concentration of dissolved ions and molecules (iii) the pressures of gases (iv) the terpreatureA. (i), (ii), (iii), (iv)B. (ii), (iv)C. (i), (ii)D. (ii), (iii), (iv)
Answer» Correct Answer - A These are the same factors that determine both the Gibbs energy difference between substances and the value of the equilibrium constant, `K`, for a chemical systeam.
