Problem- 1) Write the expressions for the rate law, inserting the proper exponents (x and y) for the concentrations of H2O2 and I-
2) Are the exponents x and y integers or fractions?
3) Evaluate the specific rate constant, k, from the rate expression for each mixture at toom temperature, and the average results.
mixture 1
mixture 2
mixture 3
average
4) Discuss as quantitatively as possible the effect of changing temperatures on the rate of the reaction.
5) What percentage of H202 has been decomposed in mixture 1 when 20mL of 02 gas have been evolved? (assume 20 degrees C and 740 mm Hg pressure.)
I just need a general explanation of it please- Thanks!
A student is examining a bacterium under the microscope. The E. coli bacterial cell has a mass of m = 0.700fg (where a femtogram, fg, is 10?15g) and is swimming at a velocity of v = 2.00?m/s , with an uncertainty in the velocity of 8.00 %
