In the reaction A + B → C, the initial concentration of A is 0.054 M. After 1.5 minutes, [A] = 0.032 M. Calculate the rate of the reaction in M/sec.

2.4 × 10⁻⁴ M/s

Explanation:

Step 1: Given data

Step 2: Convert the time to seconds

We will use the relationship 1 min = 60 s.

Step 3: Calculate the rate of the reaction

Since A is a reactant, we will calculate the rate of the reaction (r) using the following expression.

the answer is 1 i believe
