In a reaction involving the ionization of acetone, the following reaction reaction mixture was used: 5.00mL 4.0M acetone, 5.00mL 1.00M HCl, 5.00mL 0.0050M 12 and 10.0mL water.
1. what was the molarity of the acetone in the reaction mixture? (recall that M1 x V1 = M2V2)
2. the color of the above reaction mixture disappeared in 250 seconds. what was the rate of the reaction? (hint: first dertimine the initial concentration of the iodine)
1.)
M1 x V1 = M2 x V2
4 x 5 = M2 X ( 5+5+5+10)
20 = M2 x 25
M2 = 4/5
M2 = 0.8 M
2.)
Rate = [I2]/t (standard formula)
= 0.005/250
= 2 x 10-5 M/s
