A 1.0-mL volume of 0.010 M H2SO3 is added to a mixture of 12 drops of 0.010 M HIO3, 8 drops of deionized water, and 1 drop of starch solution. a color change occured after 40 seconds.
the rate of reaction is measured by the disappearance of HIO3. got the reaction mixture in this question, what is the reaction rate? ecpress the reaction rate in units of (mole HIO3/L)/(total volume L)
To determine the reaction rate, we first need to understand the stoichiometry of the reaction between H2SO3 and HIO3. From the given information, we know that the reaction between the two compounds results in the disappearance of HIO3.
To calculate the reaction rate, we need to determine the change in concentration of HIO3 over time. The change in concentration can be found using the following formula:
Reaction Rate = Δ[HIO3]/Δt
Where:
Δ[HIO3] = Change in concentration of HIO3
Δt = Change in time
In this case, the given information only mentions a color change after 40 seconds. However, we need additional data to calculate the reaction rate. The concentration of HIO3 should be provided at two time points to find the change in concentration over time.
Assuming you have the HIO3 concentration at time zero, and the HIO3 concentration after 40 seconds, you can use the given formula to calculate the reaction rate.
Once you have the reaction rate, you can express it in the desired units of (mole HIO3/L)/(total volume L). Simply divide the reaction rate (in moles HIO3 per liter) by the total volume of the reaction mixture (in liters).
Please provide the initial and final concentrations of HIO3 to proceed with the calculation of the reaction rate.
