CHE 114-01 Homework 2 t Reaction Rates t Reaction Rates To measure the speed of a car, we use miles per hour (miles/hour or mi/h or mph). To measure the rate of a reaction we use molar concentration per second (M/s). signed in as Maria Almalak 1 of 10 no Part B What is the average rate of formation of I2? Express your answer to thRe decimal places and include the appropriate units. 0.061 M Subrni Hints My Answers Give Up Review Part Correct Part C Based on your answer to Part B, what is the average rate of formation of HCl? Express your answer to three decimal places and include the appropriate units. A Value Units Submit Hints My Answers Give Up Review Part Part D This question will be shown after you complete previous question(s)
Express your answer to three significant figures and include the appropriate units. Use mi as an abbreviation for miles, and h for hours, or mph can be used to indicate miles per hour.
