In a chemical reaction, substance a reacts with substance b and forms a new substance ab. the chemical equation for this reaction is a + b = ab where a and b are the reactants and ab is the product. if you add more and more of only substance a, there will be ) less and less of product ab b) more and more of product ab with no limit to the amount of ab produced c) no change in the amount of ab produced d) more and more of product ab but limited by the amount of b 50 points
