A is correct................
Answer:
c
Explanation:
because your separating the atoms in the water
If the reaction is
X + Y → Products
Then the rate is
R = k[X]ᵃ [Y]ᵇ
Where,
R = the rate of the reaction (mol L⁻¹ s⁻¹)
k = rate constant
[X] and [Y] = concentrations of the reactants (mol L⁻¹)
a = order of the reaction with respect to X
b = order of the reaction with respect to Y
overall reaction order, n = a + b
according to the given rate expression,
rate = [a][b]³
order of the reaction with respect to 'a' is 1
order of the reaction with respect to 'b' is 3
Overall reaction order = 1 + 3
= 4
