Consider a general reaction
choli [55]

Answer:

a) K = 5.3175

b) ΔG = 3.2694

Explanation:

a) ΔG° = - RT Ln K

∴ T = 25°C ≅ 298 K

∴ R = 8.314 E-3 KJ/K.mol

∴ ΔG° = - 4.140 KJ/mol

⇒ Ln K = - ( ΔG° ) / RT

⇒ Ln K = - ( -4.140 KJ/mol ) / (( 8.314 E-3 KJ/K.mol )( 298 K ))

⇒ Ln K = 1.671

⇒ K = 5.3175

b) A → B

∴ T = 37°C = 310 K

∴ [A] = 1.6 M

∴ [B] = 0.45 M

∴ K = [B] / [A]

⇒ K = (0.45 M)/(1.6 M)

⇒ K = 0.28125

⇒ Ln K = - 1.2685

∴ ΔG = - RT Ln K

⇒ ΔG = - ( 8.314 E-3 KJ/K.mol )( 310 K )( - 1.2685 )

⇒ ΔG = 3.2694

Write the reaction of crystal violet with 1 equivalent of HCl.
tankabanditka [31]

The reaction of crystal violet with 1 equivalent of HCl will be when leuco crystal reacts with HCl to crystal violet it forms hexamethyl pararosaniline chloride.

<h3>What are crystal violet?</h3>

These are the trinary methane compounds mainly used for staining and dying of anything like bacteria or fungi and other name for it is methyl violet 10 B.

In reaction the HCl gets protonated and lone pair of nitrogen atom gives them positive charge.

3C6H6(3NH)3 + HCl will give 3C6H6(3NH)3NH4Cl + 2H

Therefore, reaction of crystal violet with 1 equivalent of HCl will be when leuco crystal reacts with HCl to crystal violet it forms hexamethyl pararosaniline chloride.

2A + B + 2C ? D + E
Amanda [17]

Answer:

C Rate =k [A]^{2} [B][C]^{-1}

Explanation:

In order to determine the correct rate law, let's use Trial 1 as baseline. Therefore:

An increase in [A] in Trial 2 by a factor of \sqrt{2} leads to an increase in the rate of reaction by a factor of 2 (i.e. the reaction rate is doubled). Thus, there is second order in [A].

Similarly,

An increase in [B] in Trial 3 by a factor of 1.667 leads to an increase in the rate of reaction by a factor of 1.667. Thus, there is first order in [B].

Futhermore,

An increase in [C] in Trial 4 by a factor of 1.71 leads to a decrease in the rate of reaction by 1.71. Thus, there is inverse first order in [C].

Therefore, the correct rate law is:

Rate =k [A]^{2} [B][C]^{-1}
