4. Write the balanced equation for CH4+Cl2„_CH2Cl2+HCl What are 3 ways you can speed the reaction in this equation?

CH4 + 2Cl2 ==>CH2Cl2 + 2HCl

Add CH4.
Add Cl2.
Add heat.

To write the balanced equation for the reaction CH4 + Cl2 ⟶ CH2Cl2 + HCl, we need to ensure that the number of atoms on both sides of the equation is equal. Here's how we do it:

1. Start with the reactants: CH4 + Cl2.
2. Count the number of each type of atom on both sides. We have:
Carbon (C): 1 on both sides
Hydrogen (H): 4 on the left, 1 on the right
Chlorine (Cl): 2 on both sides
3. Adjust the coefficients in front of the molecules to balance the equation:
CH4 + Cl2 ⟶ CH2Cl2 + 2HCl

Now let's move on to the three ways in which you can speed up this reaction:

1. Increase temperature: By raising the temperature, you provide the reactant molecules with more kinetic energy. This increases the frequency of successful collisions between molecules, leading to a faster reaction rate.
2. Increase concentration: By increasing the concentration of the reactants, you increase the number of reactant molecules per unit volume. This leads to more frequent collisions and a higher probability of effective collisions, speeding up the reaction.
3. Use a catalyst: A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process. Adding a suitable catalyst can provide an alternative reaction pathway with a lower activation energy, enabling more reactant molecules to overcome the energy barrier and react faster.

Remember, these are just three general ways to speed up a reaction. The specific conditions of the reaction, such as the nature of the reactants and the presence of any inhibitors, may require different techniques.
