10. What are the major differences between a reaction occurring in flask in the laboratory compared to a reaction occurring in a biological system?

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? Time (s) Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. a a b b d d е е Concentration (M)

For the reaction between aluminum metal and copper chloride (CuCl2) that we performed together, what is the reason that breaking a single 5 g piece of aluminum into 25 smaller pieces of aluminum (still with a total mass of 5 g ) speeds up the reaction rate.

QUESTION 7 Match the part of the rate law with the correct term. 2 NO(g) + Cl2(g) --> 2 NOCI(g) 2. rate 3.0 mol2*s A 3.0 mol2*s A. Y rate constant vorder of reaction with respect to NO vorder of reaction with respect to Cl2 В. 1 C. 2 overall reaction order D. 3 QUESTION 8 2.

Part IV Cabbage Juice Indicator Chop cabbage into small pieces until you have about 2 cups of chopped cabbage. Boil for at least ten minutes to allow time for the color to leach out of the cabbage. Allow it to cool for 15 min • Filter out the plant material to obtain a red-purple-bluish colored liquid. 1. Add 1-2 drops of cabbage juice into a small bowl 2. Add 3-5 drops of vinegar into the bowl with the cabbage juice 3. Observe Is this a chemical change or physical change? Explain? Store the excess cabbage juice in your refrigerator, you will need them for future experiments.

Analyze the following reaction and the given scenarios to discuss the relationship between volume and reaction rate. Determine which reaction will happen at a faster rate and explain why. NH3(g) + 202(g) –→ HNO3() + H2O) The first reaction is started in a gas chamber with a volume of 10 L. The second reaction is started in a gas chamber with a volume of 5 L.

Burning methane with oxygen is a highly exothermic reaction. Yet a mixture of methane and oxygen can be kept indefinitely without any reaction occurring. How is this possible?
