Question

The rate of a standard reaction is 0.01840 M/s at 25 oC. It is determined that this is too fast, and that the rate should be reduced to 0.0046 M/s. What temperature should the reaction be run at to achieve this? A. 45 oC B. 20 oC C. 15 oC D. 5 oC E. 0 oC

Answer 1

Hi there,

Your answer is given in the image attached above

Answer 2

Option B. 20 oC

Step-by-step explanation:

Thinking process:

The initial reaction takes place at: 0.01840 M/s at 25 oC.

However, the rate must be reduced to 0.0046 M/s.

It is most likely that a temperature of 20 °C is used her. This is because it offers sufficient kinetic energy to effect the reaction rate of the reaction substances.
