Does the heat released in a chemical reaction affect the rate of the reaction?

Every single reaction is either exothermic or endothermic and the temperature the reaction happens in affects the rate constant k and therefore the equilibrium of the reaction, so does, for example the heat released from an endothermic reaction affect the rate constant of that reaction, increasing the rate? this would mean that any calculated rate constants and equilibrium constants are only correct for a very short period time would it? Or is the heat released somehow accounted for in the rate constant?

Everything you have written above is correct. So good on you for having given thought to it before asking.

Yes, often reactions are exothermic and can generate heat which increases the rate constant. This is actually a big problem for many reactions, and so often times efforts are made to keep the reaction temperature low. Such runaway reaction can lead to fires, or bring you to a temperature where undesired side products form.

How do you account for this?  Very exothermic reactions are often run with strong stirring and in an ice bath to absorb the extra heat.  Another thing which helps is diluting the reactants.  This slows down the reaction and the solvent helps absorb the heat, protecting the reaction from overheating. When rate constants are measured, the temperature is carefully controlled to account for such effects.
