Chemical Reaction Spontaneity and Energy
Is the given chemical reaction spontaneous or non-spontaneous?
A. The reaction is not spontaneous and will require energy to proceed.
B. The reaction is spontaneous and will proceed without any energy input.
C. The reduction potentials cancel out and prevent any reaction.
D. The forward and reverse reactions are each spontaneous.
Answer:
B. The reaction is spontaneous and will proceed without any energy input.
When a chemical reaction has an overall reduction potential of 0.76 V, it means that the reaction will proceed spontaneously without the need for any energy input. In this case, energy will actually be released during the reaction, making it favorable to occur without external assistance.
This positive reduction potential indicates that the reaction favors the formation of products over reactants, driving it towards completion without the need for added energy. The spontaneous nature of the reaction means that it will occur naturally under the given conditions.
Therefore, the most probable scenario for the given chemical reaction is that it is spontaneous and will proceed without any energy input. Energy will be generated during the reaction, facilitating its progression in the intended direction.
