Paragraph 2 discusses two different types of thermochemical reactions. In one type of
1 answer:
Answer: The reaction is endothermic.
Explanation:
Endothermic reaction : It is a type of chemical reaction where the energy is absorbed from the surrounding. In the endothermic reaction, the reactant have less energy than the energy of products
In endothermic reaction, enthalpy terms is located on the reactant side.
Example:
Exothermic reaction : It is a type of chemical reaction where the energy is released into the surrounding. In the exothermic reaction, the energy of reactants are more than the energy of products
In exothermic reaction, enthalpy terms is located on the product side.

<u>Answer:</u> The equilibrium concentration of chlorine gas, fluorine gas and ClF gas is 0.159 M, 0.317 M and 1.002 M respectively.
<u>Explanation:</u>
We are given:
Initial concentration of chlorine gas = 0.307 M
Initial concentration of fluorine gas = 0.465 M
Initial concentration of ClF gas = 0.706 M
The given chemical equation follows:
<u>Initial:</u> 0.307 0.465 0.706
<u>At eqllm:</u> 0.307-x 0.465-x 0.706+2x
The expression of for above equation follows:
We are given:
Putting values in above equation, we get:
Neglecting the value of x = 0.993 because the equilibrium concentrations of chlorine and fluorine gases will become negative, which is not possible
So, equilibrium concentration of chlorine gas = (0.307 - x) = [0.307 - 0.148] = 0.159 M
Equilibrium concentration of fluorine gas = (0.465 - x) = [0.465 - 0.148] = 0.317 M
Equilibrium concentration of ClF gas = (0.706 + 2x) = [0.706 + 2(0.148)] = 1.002 M
Hence, the equilibrium concentration of chlorine gas, fluorine gas and ClF gas is 0.159 M, 0.317 M and 1.002 M respectively.
