Sagot :
a) The order of the reaction with respect to the complex is 1 and order with respect to Y is 2.
b) The rate constant for reaction is 2.2 × 10⁹ mol⁻²dm⁶s⁻¹.
What is order of reaction and rate constant?
The order of reaction is defined as sum of the power raised to the concentration terms . The rate constant defined as the relation between concentration and rate of the reaction, and it is also temperature dependent.
Using Rate = K [complex]ᵃ [Y]ᵇ
a) 125 = K (8.01) ᵃ (2.7) ᵇ
144= K (9.22) ᵃ (2.7) ᵇ
Divide these two equations
125/144 = (8.01/ 9.22) ᵃ
(0.868) = (0.868) ᵃ
⇒ a= 1 order with respect to complex is 1
b) R₂=K(complex)ᵃ(Y)ᵇ
125=K (8.01) (2.7) ᵇ
640=K (8.01) 6.1) ᵇ
Divide these two equations
we get, 0.195 = (0.443)ᵇ
⇒ b= 2 order with respect to Y is 2.
Now Rate constant
125=K (8.01) ¹ (2.7) ²
K = 2.2 ₓ 10⁹mol⁻²dm⁶s⁻¹.
