Determine the Rate Law and the Value of K for the Following

question 51

Multiple Choice

Determine the rate law and the value of k for the following reaction using the data provided: S₂O₈²⁻(aq) + 3 I⁻(aq) → 2 SO₄²⁻(g) + I₃⁻(aq) [S₂O₈²⁻]_i (M) [I⁻]_i (M) Initial Rate (M^-1 s^-1)
0) 30 0.42 4.54
0) 44 0.42 6.65
0) 44 0.21 3.33

• A) Rate = 120 M^-2 s^-1 [S₂O₈²⁻]²[I⁻]
• B) Rate = 36 M^-1 s^-1 [S₂O₈²⁻][I⁻]
• C) Rate = 86 M^-2 s^-1 [S₂O₈²⁻][I⁻]²
• D) Rate = 195 M^-3 s^-1 [S₂O₈²⁻]²[I⁻]²
• E) Rate = 23 M^-1/2 s^-1 [S₂O₈²⁻][I⁻]^1/2
