WebAug 5, 2024 · Answer: The rate law expression is and value of 'k' is Explanation: Rate law is defined as the expression which expresses the rate of the reaction in terms of molar concentration of the reactants with each term raised to the power their stoichiometric coefficient of that reactant in the balanced chemical equation.. For the given chemical … WebSo first, let's look at zeroth order. So zeroth order reactions have a rate law that look like this. So the rate is equal to k times the concentration of your reactant A to the zeroth power. And anything to the zeroth power is just one. So our rate is equal to the rate constant k. The units of rate are always going to be the same. black 20 feet rain gutter https://paulwhyle.com
