Question

Reaction Rates To measure the speed of a car, we use miles per hour( miles/hour or mph). To measure the rate of reaction we use molar concentration per second (M/s). Imagine that you took a road trip. Based on the information in the table, what was the average speed of your car? Express your answer to three significant figure and include the appropriate units. Now consider the following reaction and date: H_2+2IBr right arrow 2HBr+I_2 What is the average rate of information of I_2? Express your answer to three decimal places and include the appropriate units. Reaction Rates To measure the speed of a car, we use miles per hour (miles/hour or mph). To measure the rate of a reaction we use molar concentration per second (M/S). What is the average rate of information of I_2? Express your answer to three decimal places and include the appropriate units. Based on your answer to Part B, what is the average rate of formation of HBr? Express your answer to three decimal places and include the appropriate units. The question will be shown after you complete previous question(s).

Explanation / Answer

a) in 5 hours ( 3pm to 8 pm) distance travelled= 174-39= 135 miles

Average speed = distance/ time = 135/5=27.0 miles/hr

b) Average rate= (1.73-1.26)/(15-10)= 0.047 M/s

c) d[HBr]/2= d[I2]/dt

d[HBr]/dt= 2*d[I2]/dt= 2*0.047= 0.94 M/s
