Question

One glass of water is 85 degrees F and another is 40 degrees F. When an Alka Seltzer tablet is dropped into each glass, at the same time, which of the following describes the expected results? The 85 degree F glass will have an accelerated chemical reaction, because the water was warmer.

The 85 degree F glass will have an accelerated chemical reaction, because the water is cooler.

The 40 degree F glass will have an accelerated chemical reaction, because the water is cooler.

The 40 degree F glass will have an accelerated chemical reaction, because the water was warmer.

Answer 1

The 85 degree F glass will have an accelerated chemical reaction, because the water was warmer.

Step-by-step explanation:

The glass of water with the higher temperature will have an accelerated chemical reaction because the water is warmer.

The rate of chemical reaction is directly proportional to the temperature changes.

As temperature increases so is the reaction rate.

• Temperature is directly proportional to the average kinetic energy of reacting particles.
• So, the glass water at a higher temperature will have a faster reaction.
• The elevated temperature ensures increase in frequency of colliding particles in the reaction.
