4. Explain the effect that each of the following changes would have on the Rate of
Reaction in this experiment. Use your experimental results to support your
assertions.
(a) an increase in [KBrO3] 4.0(* (0-7
Vrate:
(b) an increase in [KI] 4.90 x (0²)
-7
O
(c) an increase in [HCI] .25 +10-7
(d) the substitution of higher concentration of starch solution
If there is any S₂O32-(thiosulfate ion) present, 1₂ will react
with it rather than react with starch. Every time you run the
reaction in this experiment, you will add some starch and
enough Na₂S₂O, solution to give a [S₂0,21 of 0.000200M.
The presence of starch and of S₂0,- does not interfere
with any of the reactants used, only with the 1₂.
(e) a change (increase or decrease) of reaction mixture temperature](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd3a80bdb-dbe3-4058-9ea9-0990b19198fe%2F7ae3e295-01ae-4cfd-ab56-4691b34362bf%2Fmpuz0pa_processed.jpeg&w=3840&q=75)
