Does K in rate of reaction relate to Keq?

when you are given a formula for rate of reaction like: rate=k[A], does that k have anything to do with keq?
Is that the same thing as keq?
Is it correct to say that the only thing that can change the magnitude of "rate" k and keq the temperature?

k is the rate constant (kinetic factor) and is independent of thermodynamics and equilibrium factors. It's value is defined by Arrhenius' equation (an equation you don't necessarily need to know); just realize however, the rate constant is unique for a given reaction and is altered by temperature, frequency of collision, and number of collisions with proper orientation. All of these influence the rate constant. The actual Rate of the reaction varies with concentration of reactant. However, at equilibrium (because the concentration of products and reactants are constant) and their respective rates are equal, what we can say is that the ratio of the: Rate constant of the forward reaction / Rate constant of the reverse reaction equals Keq.

You mean lower case "k" is a kinetic factor, while capital "K" is a thermodynamic factor.

You beat me to it, lol. I just edited my post for clarification.
