Rate law of chemical reaction

Question

Assignment:

The rate of the following reaction in aqueous solution is monitored by measuring the rate of formation of (I₃^-). The data obtained is listed in the table.

(S₂O₈^2-) + (3I^-) ----> (2SO₄^2-) + (I₃^-)

Experiment ([S₂O₈]^2-), M ([I]^-),M Initial rate, M s^1-
1 0.038 0.060 1.4 x 10^-5
2 0.076 0.060 2.8 x 10^-5
3 0.076 0.120 5.6 x 10^-5

Q1.) Determine the order of the reaction with respect to (S₂O₈^2-), with respect to (I^-), and the overall order.(Choose the correct letter choice.)

A) Order with respect to (S₂O₈^2-)
a.zeroth
b.first
c.second
d.third
e.fourth

B) Order with respect to (I^-)
a.zeroth
b.first
c.second
d.third
e.fourth

C) Order of the reaction
a.zeroth
b.first
c.second
d.third
e.fourth

Q2.) What is the value of the rate constant k?(in M^-1 s^-1)
Q3.) What is the initial rate of reaction for [S₂O₈^2-] = 0.023 M and [I^-] = 0.040 M? (in M^s-1)
