Consider a reactant with an order of 1: what effect does that reactant have on the rate equation when the concentration is doubled 1) the reaction rate is double with respect to that reactant 2) the order doesnt effect the reaction so there will be no change 3) the reaction rate quadruples with respect to that reactant. 4) the reaction rate isn't changed by individual reactants so there will be no change.

1) The reaction rate is double with respect to that reactant

Explanation:

Hello,

By considering the rate law:

If we double the reactant A concentration, by definition, the rate will be doubled as well since the power is one (order 1), this could be proved just by checking it out in the rate law.

Best regards.

r just means there's a number of carbon in teh chain. for example rcooh means that after x number of carbon, the chain ends with cooh.

explanation:

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
