see experiment 1 and 2:
[OCl-] doubles
[I-] is constant
rate doubles
so, order of OCl- is 1
see experiment 1 and 3:
[OCl-] is constant
[I-] doubles
rate doubles
so, order of I- is 1
Rate law is:
rate = k*[OCl-]*[I-]
B)
rate = k*[OCl-]*[I-]
Put values from 1st row of table in rate law
rate = k*[OCl-]*[I-]
1.36*10^-4 = k*0.0015*0.0015
k = 60.44 M-1.s-1
Answer: 6.0*10^1 M-1.s-1
C)
rate = k*[OCl-]*[I-]
rate =60.44*0.0015*0.0056
rate = 5.08*10^-4 M/s
Answer: 5.1*10^-4 M/s
