The disaccharide lactose can be decomposed into its constituent sugars galactose and glucose. This decomposition can be accompli
n200080 [17]

Answer:

Rate  = 116m⁻¹s⁻¹[lactose][H]⁺

Explanation:

the formula for rate of reaction is given as

Rate = k[lactose]∧α[H]⁺∧β

we solve for the value of α and β

([lactose]₁/[lactose]₂)∧α

α = \frac{ln\frac{0.00116}{0.00232} }{ln\frac{0.01}{0.02} }

when we divide this equation

α = \frac{ln0.5}{ln0.5}

α = 1

we find β

R₁/R₂ = 0.01/0.02(0.001/0.001)∧β

0.00116/0.00232 = 0.5(1)∧β

β = 1

Rate = k[lactose]∧α[H]⁺∧β

we have to find the value for k

k = 0.00116/0.01(0.001)

k = 0.00116/0.00001

= 116m⁻¹s⁻¹

<u>Rate = 116m⁻¹s⁻¹[lactose][H]⁺</u>
