Question

Use the integrated rate law for the process to calculate the time in days it will take for the concentration of alanine to decrease from 1 mm to 0.5 mm.

a) Insufficient information
b) 1 day
c) 2 days
d) 3 days

Answer 1

Without the reaction order or rate constant, we cannot determine the half-life of the alanine concentration decrease; thus, the answer is 'Insufficient information.'

Step-by-step explanation:

To calculate the time it will take for the concentration of alanine to decrease from 1 mm (millimolar) to 0.5 mm, we need to know the order of the reaction and the rate constant. However, the necessary information such as the reaction order or the rate constant is not provided. Without this information, we cannot accurately determine the time needed for the concentration to drop by half, known as the half-life of the reaction. Therefore, the correct answer to this question is (a) Insufficient information.
