4. For the reaction A + 2B → C, the rate law is
The rate continuous : b. 1/ M² · s
The reaction rate (v) reflects the change in the concentration the the substance (changes in enhancement to concentrations because that reaction products or changes in concentration reduction because that reactants) every unit time.
For A + B ---> C + D
Can it is in formulated:
v = reaction speed, M / s
k = constant, mol¹⁻⁽ᵃ⁺ᵇ⁾. L⁽ᵃ⁺ᵇ⁾⁻¹. S⁻¹
a = reaction order come A
b = reaction order come B
Units that the rate consistent - k count on price law, so it is distinctive for the details reaction
So because that the rate law :
