1)
A)What is meant by the heat capacity of a body? How does it affect the value of the rate constant? (For example, would a large heat capacity for the body imply a larger or a smaller value of “k”?
B) would the rate constant (“k”) be the same or different for the heating and cooling processes in an experiment?

The value of the heat capacity for a substance depends on
whether it’s measured under constant pressure conditions or
constant volume conditions. The constant-pressure molar heat
capacity is given by
= (dq/dT)P
and the constant-volume heat capacity is given by
= (dq/dT)V
Note that we use d instead of
because q is not a state function of temperature, volume, and
pressure; its value depends on how we execute the process.
Here are several questions regarding heat capacity.
