Explanation:
Step 1: Data given
For the reaction aA + bB ⇆ cC + dD
Kc = [C]^c * [D]^d / [A]^a [B]^b
a. SbCl5(g) ⇄ SbCl3(g) + Cl2(g)
Kc = [Cl2]*[SbCl3] / [SbCl5]
b. 2 BrNO(g) ⇄ 2NO(g) + Br2(g)
Kc = [Br2]*[NO]² / [BrNO]²
c. CH4(g) + 2 H2S(g) ⇄ CS2(g) + 4 H2(g)
Kc = [H2]^41 * [CS2] / [H2S]²*[CH4]
d. 2CO(g) + O2(g) ⇄ 2CO2(g)
Kc = [CO2]² / [O2][CO]²
Answer:
Achol
Explanation:
Reduction of other aldehydes gives primary alcohols. Reduction of ketones gives secondary alcohols. The acidic work-up converts an intermediate metal alkoxide salt into the desired alcohol via a simple acid base reaction.
Answer: 48,501 J/mol
Explanation:
1) Action barrier = activation energy = Ea
2) Data:
i) T₁ = 12°C = 12 + 273.15 K = 285.15K
ii) T₂ = 22°C = 22 + 273.15 K = 295.15 K
iii) rate constant = k: k₂ / k₁ = 2
iv) Ea = ?
3) Formula:
Arrhenius' law gives the relationship between the constant of reaction and the temperature:
4) Solution
By arranging the formula, you get:
㏑[k₂/k₁] =Ea/R [1/T₁ - 1/T₂]
Replace k₂ = 2k₁; T₁ = 285.15; and T₂ = 295.15
ln[2] = Ea/8.314 J/K mol × [1/285.15 - 1/295.15]K
Ea = ln [2] × 8.314 J/K mol / [1.18818×10⁻⁴K] = 48,501 J/mol
Answer:
Protons and neutrons are made up of smaller subatomic particles. When protons or neutrons get close enough to each other, they exchange particles (mesons), binding them together. Once they are bound, it takes considerable energy to break them apart.
Enzymes speed up chemical reacations
endothermic is when you are putting energy in it controls the rate of how fast it goes not to slow not to fast
