Given the balanced equation:

2 ki + f2 --> 2 ki + i2

which type of chemical reaction does this equation represent?

In our case, the equation  2KI + F2 → 2 KI + I2 is a single-replacement (also called single- displacement) reaction.

Explanation:

Step 1: The balanced equation:

2KI + F2 → 2 KI + I2

Step 2: What kind of reaction

Since we start with 2 reactants and end with 2 products, we can say it won't be a synthesis or decomposition reaction.

In our case, It looks like it's a replacement reaction.

- A single-replacement reaction is a reaction in which one element replaces a similar element in a compound. The general form of a single-replacement reaction is:  A+BC→AC+B

where element  A  is a metal and replaces element  B , also a metal, in the compound.

When the element that is doing the replacing is a nonmetal, it must replace another nonmetal in a compound.

- A double-replacement reaction is a reaction in which the positive and negative ions of two ionic compounds exchange places to form two new compounds. The general form of a double-replacement reaction is:  AB+CD→AD+BC

In our case, the equation  2KI + F2 → 2 KI + I2 is a single-replacement (also called single- displacement) reaction.

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
