Question: What factors affect the energy yield from an energy source-TEA reaction?
- The element in the energy source that is oxidized.
- The oxidation state of the element in the energy source that is oxidized.
- The extent to which the element in the energy source is oxidized in the reaction.
- The TEA and the element in the TEA that is reduced.
Answer: Option C- Three of the above. The factors that affect the energy yield from an energy source- TEA reaction are the element in the energy source that is oxidised, the oxidation rate of the element, extent the element iss being oxidised in the reaction and also the molecular mass of the energy source.

There are several factors that affect the rate of a reaction. These factors include temperature, activation energy, steric factors (orientation), and also collision frequency, which changes with concentration and phase. All the factors that affect reaction rate can be summarized in an equation called the Arrhenius equation: k=Ae−Ea/RT, where k is the rate constant, A is the frequency factor, Ea is the activation energy, R=8.314 J mol−1 K−1 is the gas constant, and T is the absolute temperature. A certain...
