Compute the rate of reaction in ms

Reference no: EM13175907

Consider the data below representing a run for the Clock Reaction. If the volumes of reagents indicated were combined and 219 seconds elapse before the color appears, calculate the rate of reaction in M/s.

0.50 mL 0.00050 M Na2S2O3
0.50 mL 0.010 M KI
0.50 mL 0.040 M KBrO3
0.25 mL 0.100 M HCl
0.75 mL DI H2O

1-2 drops 1% starch indicator (negligible volume)

A) 2.3 x 10-6 M/s
B) 9.1 x 10-7 M/s
C) 4.6 x 10-7 M/s
D) 3.8 x 10-7 M/s
E) 7.6 x 10-8 M/s
