Can someone explain 5.13 and how to get the initial reaction rate?

I am assuming you mean 15.13 or else I would be doing the wrong problem! First, you have to convert the grams of reactants given into moles, and then from moles to their respective molarity values. You get these values to be 0.347 mol/L and 0.001 mol/L. Then, multiple these values and the given k together, nd that should help you reach the correct answer.

Convert grams to mols using molar masses of H2 and I2. Then use .750 L to convert it to Molarity. You should have roughly 0.35 mol/L H2 and 0.001 mol/L I2.

Rate = k[H2][I2]

Rate = 2.2 x 10-5 mol/(L x S)

Return to “Method of Initial Rates (To Determine n and k)”
