Answer:
1.62 × 10⁻³ M s⁻¹
Explanation:
Let's consider the following reaction.
2 NO₂ + F₂ = 2 NO₂F
The generic rate law is:
rate = k × [NO₂]ᵃ × [F₂]ᵇ
where,
- a and b: reaction orders with respect to the reactants
The reaction is first order in NO₂ and first order in F₂ and the rate constant is k = 1.58 × 10⁻⁴ M⁻¹ s⁻¹.
The rate law is:
rate = 1.58 × 10⁻⁴ M⁻¹ s⁻¹ × [NO₂] × [F₂]
When [NO₂] = 2.84 M and [F₂] = 3.60 M, the reaction rate is:
rate = 1.58 × 10⁻⁴ M⁻¹ s⁻¹ × 2.84 M × 3.60 M
rate = 1.62 × 10⁻³ M s⁻¹
Answer:
2NaOH + CO2 -> Na2CO3 + H2O
1) Find the moles of each substance
2) Determine the limitting reagent
∴ Carbon dioxide is limitting as it has a smaller value.
3) multiply the limiting reagent by the mole ratio of unknown over known
n(H2O ) = 0.3976369007 × 1/2
= 0.1988184504 moles
4) Multiply the number of moles by the molar mass of the substance.
m = 0.1988184504 × (1.008 × 2 + 16.00)
= 0.1988184504 × 18.016
= 3.581913202 g
