Question

Somebody help me please :(

1. Based on the data, determine which is higher Hreactants or Hproducts in both reactions. (DH = DHrxn = Hproducts – Hreactants) Support your answer with relevant data from the experiment.

2. Why is a lower temperature increase expected in reaction B than Reaction A?

Results Reaction | Initial | Max Temp. | Reaction | Rate | 11| Exothermic Temp Temp. Change Rate Ranking + n000 Endothermic (Exothermic 2 Exothermic (NaOHtHCD23.328.76.4 °C.64 oC °C/sec oC 21.4 26 4.7°C36 NaOH + Vinegar) oc/sec

Explanation / Answer

Solution(1): So based on the data: For both the reactions Hproducts is higher than Hreactants because DH is negative for both the reactions.and we know  DH = DHrxn = Hproducts – Hreactants . so this equation justifies our concluision.

Solution(2): As we can see the rate of the reaction for B is lower than the rate of reaction of B. so the reaction B will take place slowly and the temprature change will be less for reaction B.
