Answer:
λ = 6.25 × 10⁻¹⁰ m
x-ray
General Formulas and Concepts:
Speed of Light = Wavelength times Frequency
Explanation:
<u>Step 1: Define</u>
C = 3.0 × 10⁸ m/s
ν = 4.80 × 10¹⁷ Hz (s⁻¹)
λ = unknown
<u>Step 2: Solve for wavelength</u>
3.0 × 10⁸ m/s = λ(4.80 × 10¹⁷ Hz)
λ = 6.25 × 10⁻¹⁰ m
<u>Step 3: Check</u>
<em>We are given 3 sig figs. Follow sig fig rules.</em>
6.25 has 3 sig figs. No changes necessary.
<u>Step 4: Identify</u>
6.25 × 10⁻¹⁰ m is in the x-ray spectrum according the the Electromagnetic Spectrum
Answer: Reaction A: pi + glucose ⇒ glucose-6-phosphate + H2O ΔG = 13.8 kJ/mol
Reaction B: pi + frutose-6-phosphate ⇒fructose-1,6-biphosphate + H2O ΔG = 16.3kJ/mol
Explanation: ΔG is the representation of the change in Gibbs Free Energy and relates enthalpy and entropy in a single value, which is:
ΔG = ΔH - TΔS
where:
ΔH is enthalpy
T is temperature
ΔS is entropy (measure of the )
It can also predict the direction of the reaction with the conditions of temperature and pressure being constant.
When the change is positive, the reaction is non-spontaneous, which means the reaction needs external energy to occur. If the change is negative, it is spontaneous, i.e., happens without external help.
Analyzing the reaction, we see that reaction A and B have a positive ΔG, while reaction C is negative, so the reaction that are unfavorable or nonspontaneous are <u>reactions A and B</u>.
a. stereospecific: 100% inversion of configuration at the reaction site
