Consider the following system at equilibrium at 573 K: 2NOCl(g) + 18.4 kcal2NO(g) + Cl2(g) If the TEMPERATURE on the equilibrium
Ghella [55]

Answer:

After increasing the temperature of the system:

The reaction must: Run in the forward direction to restablish equilibrium.

Already at equilibrium. The concentration of Cl2 will: Increase.

Explanation:

The equilibrium constant, for an endothermic reaction (ΔH ° positive), increases with increasing temperature.

The principle of Le Châtelier indicates that if an equilibrium mixture is heated, and consequently its temperature increases, there will be a net reaction in the direction that counteracts the disturbance caused by the increase in temperature. For an endothermic reaction, the direct reaction absorbs energy in the form of heat.

Consequently, the equilibrium shifts to the side of the products, which means that Kc increases with increasing temperature.

Draw a structure for the product of nucleophilic substitution obtained on solvolysis of tert−butyl bromide in methanol
DENIUS [597]

Answer:

methyl tert-butyl ether is produced as a product

Explanation:

  • Nucleophilic substitution in solvolysis reaction of tert-butyl bromide goes through S_{N}1 mechanism.
  • Because Br is a good leaving group due to it's large size and high polarizability and methanol is an weak nucleophile.
  • In the first step, tert-butyl cation is produced. In the second step, methanol attacks the carbocation and produce methyl tert-butyl ether after deprotonation.
  • Reaction and structure of product has been shown below.
