How can I convert a rate constant from mol to t/M.I have 0.00012 mol of AcH
present at 5min .Know I want to calculate the concentration at this time ( [AcH]t / M ) . How would I work this out .Please help this is for a lab writeup for tomorrow .
To convert a rate constant from mol to M⁻¹·s⁻¹, you need to know the stoichiometry of the reaction. The rate constant is typically determined experimentally and is specific to a particular reaction.
In your case, you mentioned that you have 0.00012 mol of AcH present at 5 minutes. To calculate the concentration of AcH at this time ([AcH]t / M), you need to know the volume of the solution in which AcH is dissolved.
Assuming you have the volume (V) of the solution, you can use the formula:
[AcH]t / M = (moles of AcH) / (volume of solution in liters)
1. Convert the time from minutes to seconds to match the units of the rate constant. There are 60 seconds in a minute, so 5 minutes is equal to 5 * 60 = 300 seconds.
2. Determine the volume of the solution in liters. If you have the volume in milliliters (mL), divide it by 1000 to convert to liters.
3. Calculate the concentration using the formula above:
[AcH]t / M = (0.00012 mol) / (V L)
Remember to use the appropriate unit for volume (liters) and provide the answer with the correct number of significant figures.
