Give five ways of increasing the rate of the following reaction: H2(g)+Br2(g) -> 2HBr(g)?

1. Increase the concentration (or partial pressure) of H₂
2. Increase the concentration (or partial pressure) of Br₂
3. Increase the total pressure by reducing the volume of the reaction system
4. Increase the temperature
5. In the presence of uv light (to provide light energy for bond breaking of Br-Br bonds)

(Adding a catalyst may increase the reaction rate, but no catalyst has been found for the reaction.)
(As there is no solid reactant, "increase the surface area" is not accepted as a way to increase the reaction rate.)

- Increase temperature
- increase pressure of gas
- add a catalyst
-increase surface area of reactants (more collisions)

thats all I got sorry good luck on number 5
