Solution A, while in a 1.0 cm cell, has an absorbance of 0.390 and a [Cu2+] = 0.0283 M. Then, 6.57 mL of solution A is diluted with pure water to 100.0 mL. What is the absorbance of this diluted solution? I tried but I still don't get it. Can anyone pleas...

If the rate of a reaction doubles for every 10 C rise in temperature, how much faster does the reaction proceed at 45 C than at 25 C? Please help, thanks a lot!

If the Kf value is known to be 2.0 x 10^3. The experimental values for Kf were found to be 1.0 x 10^3, 2.0 x 10^3, 3.0 x 10^3, 1.5 x 10^3 and 1.0 x 10^3. Using the absolute values of differences, calculate the average deviation from Kf. Please show me the...
