ΔG° = 14.1 kJ/mol
For the reaction A → B, <em>K</em> = [B]/[A].
If [A] = 240 and [B] = 1, then
<em>K</em> = 1/240 = 4.167 x 10^(-3)
The relationship between Δ<em>G</em>° and <em>K</em> is:
Δ<em>G</em>° = -<em>RT</em>ln<em>K</em>
where
<em>R</em> = the gas constant = 8.314 J·K^(-1)mol^(-1)
<em>T</em> = the Kelvin temperature
In this problem, <em>T</em> = (37 + 273.15) K = 310.15 K
∴ #Δ<em>G</em>° = -8.314 J·K^(-1)mol^(-1) × 310.15 K × ln(4.167× 10^(-3)
= -2579 × [-5.481 J·mol^(-1)] = 14 100 J·mol^(-1) = 14.1 kJ/mol
Note: We should expect Δ<em>G</em>° to be positive because <em>K</em> < 1.
Answer:
Explanation:
(a) Balanced equation
2HCl + Ca(OH)₂ ⟶ CaCl₂ + 2H₂O
(b) Moles of Ca(OH)₂
(c) Moles of HCl
(d) Molar concentration of HCl
The molar concentration of the HCl was 
The answer is 1.83 moles of Na.
Answer: decrease the temperature of the reaction
Explanation:
CH3COOH + CH3CH2OH ⇌ CH3COOCH2CH3 + H2O
The formation of an ester is an exothermic reaction. Therefore, a decrease in the temperature of the reaction will favour the production of ester.
