does k change if rxn is multiplied?

If you find the rate constant on a table but the rxn you have is multiplied by 2 of the table rxn, would you mulitply the Kr (rate constant) by 2, or raise it to the 2 power? Or is Kr independent of the reaction?

The Kr shouldn't really change as when you multiply the rxn, both the reactants and products will be affected and should cancel the multiplication.

it shouldn't change when rxn is multiplied

k should not change even if the coefficients are changed.

Because k represents the rate constant, the value of k will never change for a unique reaction. That is to say, k itself will stay stagnant for that particular reaction. "Multiplying the table" by a factor of two would just change the concentration of the reactants, which would change the rate of the reaction, but not the rate constant.

k is a constant for the equation so it should not change if the rxn is multiplied

k doesn't change because it is the same value for the equation.
