Answer
See explanation below.
Work Step by Step
Chemical reactions usually occur with small changes in energy whereas there is huge difference in energy during nuclear reaction.
a.Increasing temperature increases the rate of a chemical reaction, but has no effect on nuclear reaction.
b.But increasing reactants, increases the chemical and nuclear reactions
c.If the reactant is limiting in chemical reaction, more reactant produces more product and the yield increases.If more radioactive reagent results in more decay product, higher reactant concentration increases the yield in a nuclear reaction.
