Answer:
Explanation:
You can infere the units of the rate constant for an <em>overall order 2 reaction </em>departing from the simplified case of a two identical reactants combined in a single elementary step:
- A + A → Products (single elementary step equation)
For that equation the differenttial form of the rate of reaction is:
- r = - d [A] / dt = K [A]²
The units of [A] are M¹ (i.e. M), and the units of - d [A] / dt are M¹ s⁻¹ . . . ( M stands for molar concentration)
Substituting the unis on both sides of the rate equation you get:
Solving for K:
- K = M¹ s⁻¹ M⁻² = M⁻¹ s⁻¹, which is the final result.
Answer:
sound waves in air and water are longitudinal. Their disturbances are periodic variations in pressure that are transmitted in fluids. Figure 13.5 the wave on a guitar string is transverse
I’m not sure if this s what your asking but here’s the formula, 6co2 + 6h2o + suns energy + c6h12o6 + 6o2
Carbon dioxide + water + Sun’s energy + Sugar (Glucose) + Oxygen
7 + 5 = 12. But there is also electrons, and there is an equal amount. The atomic mass is 17.
Description: The standard enthalpy of reaction is the enthalpy change that occurs in a system when matter is transformed by a given chemical reaction, when all reactants and products are in their standard states.
