Web13 mrt. 2024 · Add together the heats of formation for the products, CO + H2, which is –110.53 kJ/mol + 0 kJ/mol = –110.53 kJ/mol. Subtract the sum of the heats of formation of the reactants from that of the products to determine delta H: delta H = –110.53 kJ/mol – (–285.83 kJ/mol) = 175.3 kJ. Did you find this page helpful? WebSo the units of k for a second order reaction are one over molar, molar-seconds. so these are the three most common molecularities that you might see in a chemistry class. And sometimes, you have reactions that aren't zeroth, first, or second order, and whenever that happens, you can always use the rate law to find the units of the rate constant k. binghamton to cortland ny
