The rate of a reaction is how quickly the reaction goes to completion. If two reactions have the same amount of reactant, increasing the rate does not increase the amount of product produced, it simply reduces the time that it takes to make the product. Using the internet , research the four factors below that affect the rate of a chemical reaction. 1. Reactant concentration ( explained with details and add graphs to explain what you wrote for each one of them) 2. pressure ( explained with details and add graphs to explain what you wrote for each one of them) 3. Temperature ( explained with details and add graphs to explain what you wrote for each one of them) 4. Presence of a catalyst. ( explained with details and add graphs to explain what you wrote for each one of them) Your work should be written in complete sentences, and assume your audience is grade 11 chemistry students who do not understand this unit. Make sure all research is put into your own words!

Use the graph to calculate the following. a.) Calculate the average rate of the reaction between 10 and 20 s. b.) Calculate the instantaneous rate of the reaction at 30 s. c.) Calculate the instantaneous rate of formation of O₂ at 50 s. d.) If the initial volume of the H₂O₂ solution is 1.5 L, what total amount of O₂ (in moles) is formed in the first 50 s of reaction?
Consider the following general reaction for which gases A and B are mixed in a constant volume container: A(g) + B(g) -> C(g) + D(g) Match what happens to the rate of the reaction under the following changes: (consider each change separately) v all of gas B is removed from the container more gas A is added to the container the temperature of the container is increased there is no change to the reaction rate ya catalyst is added to the container I. the reaction proceeds at a faster rate v gas D is also added to the container the reaction proceeds at a slower rate II. some of gas B is removed from the container Iy the reaction does not proceed at all the volume of the container is increased

The rate of a reaction is how quickly the reaction goes to completion. If two reactions have the same amount of reactant, increasing the rate does not increase the amount of product produced, it simply reduces the time that it takes to make the product.

A gas sample of Br2 and H2 is irradiated with light with a wavelength range between 440 and 500 nm. It is known that this radiation has sufficient energy to obtain HBr. With this data you can say:a) All the molecules present will give rise to HBr, because the wavelengths are appropriate to activate all the reactants.b) The rate of HBr formation depends directly on the concentration of H2 in the sample.c) The rate of HBr formation depends directly on the concentration of Br2 in the sample.d) If the sample is irradiated with a wavelength of 580 nm, there is no guarantee that HBr will be obtained.
