Answer
## Step 1:Convert 3 minutes and 20 seconds to seconds. 3 minutes = 180 seconds20 seconds = 20 secondsTotal time = 180 seconds + 20 seconds = 200 seconds## Step 2:Substitute the given values into the formula:
## Step 3:Calculate the mean rate of reaction:
Explanation
## Step 1:First, we need to convert the time from minutes to seconds for consistency in units. Given that 1 minute is equal to 60 seconds, we can convert 3 minutes and 20 seconds into seconds.## Step 2:The mean rate of a reaction is calculated by dividing the total change in the quantity of a reactant or product by the total time taken for the reaction. In this case, we are given the total quantity of gas produced (24 cm³) and the total time taken for the reaction (3 minutes and 20 seconds). ### The formula for the mean rate of reaction is: **
**## Step 3:Substitute the given values into the formula to calculate the mean rate of reaction.
