Answer:
4.3 × 10⁻⁵ M s⁻¹
Explanation:
Step 1: Given data
- Rate constant (k): 2.20 × 10⁷ M⁻¹s⁻¹
- Concentration of NO ([NO]): 3.3 × 10⁻⁶ M
- Concentration of O₃ ([O₃]): 5.9 × 10⁻⁷ M
- First order with respect to both NO and O₃
Step 2: Write the balanced reaction
NO + O₃ ⇒ NO₂ + O₂
Step 3: Calculate the reaction rate
The rate law is:
rate = k × [NO] × [O₃]
rate = 2.20 × 10⁷ M⁻¹s⁻¹ × 3.3 × 10⁻⁶ M × 5.9 × 10⁻⁷ M
rate = 4.3 × 10⁻⁵ M s⁻¹
Zn(HCO3)2 is the compound for Zinc Bicarbonate
a balanced chemical equation occurs when the number of the atoms involved in the reactants side is equal to the number of atoms in the products side.
Answer:
limiting reactant started with/limiting reactant needed=
= 3.5 mol/3.5 mol=1:1
Explanation:
2H2 + 1 O2 ---> 2 H2O
from reaction 2 mol 1 mol
given 3.5 mol 2.5 mol
needed 3.5 mol 1.75 mol
Excess reactant O2, Limiting reactant H2.
Limiting reactant will be used completely.
So, limiting reactant started with/limiting reactant needed=
= 3.5 mol/3.5 mol=1:1
