A 100 mL of a 0.100 M solution of vinegar (acetic acid, CH3COOH) is mixed with 100 mL of a 0.100 M baking soda (sodium bicarbonate) solution and a reaction proceeds that generates carbon dioxide, water and sodium acetate. What is the reaction rate if 0.140 grams of carbon dioxide are produced over 4.00 seconds? The units are mol/s.
