What is the relative rate of change of each species in the reaction?

Question

ch 17 q 1

The rate of the given reaction is 0.540 M/s.0.540 M/s.

A+4B⟶2CA+4B⟶2C

What is the relative rate of change of each species in the reaction?

Δ[A]

Δ𝑡= ____M/sM/s

Δ[B]

Δ𝑡= ____M/sM/s

Δ[C]

Δ𝑡=____M/s

^Those are fractions

Answer 1

A + 4B ⟶ 2C

The rate of the given reaction is k = 0.540 M/s

Each "mole reaction" is equivalent to 1 mole of A, 4 moles of B and 2 moles of C

Therefore

Δ[A] / Δ𝑡 = - k = - 0.540 M/s (negative because A is a reactant and is consumed in the reaction)

Δ[B] / Δ𝑡 = - 4 k = - 2.16 M/s (negative because B is a reactant and is consumed in the reaction)

Δ[C] / Δ𝑡 = 2 k = 1.08 M/s (positive because C is a product and is created in the reaction)
