![16.31 The reaction n-C3H,Br + S₂O3 → C3H₂S₂O3 + Br¯
in aqueous solution is first order in C3H,Br and first-order in
S₂O3-. At 37.5°C, the following data were obtained (where
cº = 1 mol/dm³ and 1 ks
10³ s):
10³ [S₂0-]/cº
86.3
76.6
66.8
t/ks
2.010 5.052
11.232
The initial C3H,Br concentration was 39.5 mmol/dm³. Find the
rate constant
=

Follow-up Question
since it's the first order , Can i just use the equation ln(CA) = lnCA0 - k1t , with x =t and y = ln(CA) ?
However when I put on the data in the calculator, it doesn't show the k1 I want although I have change the units of time from ks to s and for the concentration, I had divided by 10^3
