for question 3 im getting 96.234 sec but it says itswrong but close to the answer.
for activation energy.. i get 24.6 kj/mol but its wrong
3) You mix together in the proper manner the followingVOLUMES:
0.0100 M Potassium iodide...14.7 mL
0.0010 M Sodium thiosulfate...5.6 mL
Distilled water...22.7 mL
0.0400 M Potassium Bromate...11.7 mL
0.100 M Hydrochloric acid...5.6 mL
Using the rate constant and rate equation from problem 2),
exponent c is 1.92
exponent constant K 4.7125
CALCULATE the time to turn blue...____________ sec(c)
4) A plot of log Rate vs 1/T gives a best straightline which goes through....
1/T = 0.00300, log rate = -4.46
and 1/T = 0.00352, log rate = -6.00.
CALCULATE:
The Slope of the line...is -2961.53_(d)
The Activation Energy (Ea)(Kj/mol)...______________(e)
thanks in advance
