Question

A student is pouring baking soda in a beaker of vinegar at room temperature (23 °C). A chemical reaction occurs between the vinegar and baking soda. Which of the following conditions would result in the fastest reaction?

A) Pour 10g of baking soda into 250ml of vinegar at 33 °C.

B) Pour 10g of baking soda into 250ml of vinegar at 23 °C.

C) Pour 20g of baking soda into 500ml of vinegar at 13 °C.

D) Pour 20g of baking soda into 500ml of vinegar at 23 °C.

Answer 1

The conditions that would most likely produce the quickest reaction would be as follows:

C). Pour 20g of baking soda into 500ml of vinegar at 13 °C.

• The condition that is most likely to generate the reaction at the fastest rate would include 20g(baking soda) along with 1/2 liter of Vinegar at the temperature of 13°C.
• The reason behind this is that the reaction that takes place between baking soda and vinegar exemplifies an endothermic reaction that produces CO2.
• The higher temperature produces a quicker reaction time and an adequate ratio of sodium bicarbonate and vinegar, the reaction takes place quickly and effectively.

Thus, option C is the correct answer.
