Which of the following statements are false with respect to rate laws? Select all that apply. □ Catalysts can't be included in the rate law. □ Intermediates can't be included in the rate law. □ Products can't be included in the rate law. □ Rate Laws don't have to include a rate constant.□ Reactants can't be included in the rate law. □ The orders with respect to each species is directly related to the coefficient in the overall reaction

Consider this reaction: Br CH₂OH + Br-Br H₂CO The mechanism proceeds through a first cationic intermediate, intermediate 1. Nucleophilic attack leads to intermediate 2, which goes on to form final product. In cases that involve a negatively charged nucleophile, the attack of the nucleophile leads directly to the product. Year Hot Br + CH₂OH Br Intermediate 1 Intermediate 2 (product) In a similar fashion, draw intermediate 1 and intermediate 2 (final product) for the following reaction. Br H Br₂ + NaBr + H2O H H H NaOH . Pay attention to the reactants, they may differ from the examples. In some reactions, one part of the molecule acts as the nucleophile. Structures are provided for you to modify in the sketchers below. . • You do not have to consider stereochemistry. • Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner. Separate intermediate 1 and intermediate 2 using the symbol from the dropdown menu. Sn [F H On [F I Br -OH HH…
