Kinetic studies of the reaction X + 2Y → W + 2Z yield the following data: Concentration of X (mol) Concentration of Y (mo) Rate (mol L8 0.100 0.150 8.00 x 10 3 0.100 0.300 1.60 x 102 0.200 0.150 3.20 x 102 What is the order of this reaction with respect to X: and Y: Calculate k, report your answer with 3 significant figures, do not include the unit:

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

Which of these are factors that impact rate of reaction? temperature reactant concentration presence of a catalyst O reactant particle size

Consider the reaction: H2 (g) +I2 (g) → 2 HI (g) A chemist performed an experiment and monitored the concentration of I2 during the course of the reaction. The red line in the graph below represents the results obtained. Which line in the plot would best represent how the concentration of HI changes during the course of the reaction?
