5. If reaction is not stopped, then the product will be formed continously until the substrate is available. Once the substrate becomes limiting, the reaction will stop on its own. In order to make the reaction go indefinitely, the substrate must be supplied continously.
6. The phenomenon where one of the product is used as an inhibitor to stop the overall reaction is known as feed back inhibition. It is done when the final product is not required anymore and formation of anymore product will result in wastage of energy. So, in this case the reaction is stopped by feedback inhibition.
Hope it helps, Good luck

6. Vinegar is 5.00% (m/v) acetic acid (CH3COOH). How many milliliters of vinegar would you need to react with an excess of baking soda (NaHCO3) in order to generate 10.0 L of carbon dioxide gas at 1.05 atm and a temperature of 25.0°C? 7. Shown below is the aqueous reaction of KNOX, HCl, and SnCl2. 2 KNO2 (aq) + 6 HCl(aq) + 2 SnCl2 (aq) → 2 SnCla (aq) + N20 (g) + 3 H20 (1) + 2 KCl (aq)...

You will be observing a reaction in this lab. As with most reactions, this reaction occurs by the breaking of some bonds in the reactants and the formation of new bonds in the products. During the reaction, the gas that is produced will fizz away. After the reaction is complete, one of the products can be removed. Then you will determine the mass of the other product this will be your actual (or experimental) yield. You will compare this value...

CONTEXT So we did an Sn1 reaction in chem lab to convert t-butyl alcohol to t-butyl chloride by the following reaction C4H10O + HCl --> C4H9Cl + H2O We did this by mixing the HCl and the t-butyl alcohol in a separatory funnel, then we collected the organic layer that formed and vacuum distilled the product. QUESTIONS What is something that could cause a low yield in this experiment? we got a 26% yield, I was thinking maybe heating up...
