Assignment 1. The reaction 2NO (g) tCL (g) 2NOCI (g) was studied at - 10 C. The following results were obtained where Rate =-A[Ch] At [2NO), (mol / L) Chle (mol/L) Initial Rate (mol /L min) 0.18 0.10 0.10 0.10 0.20 0.36 0.20 0.20 145 a) What is the rate law b) What is the value of the rate constant

50 Concentration (mol/L) es Notes.pdf Reaction Rates Reaction rates are measured in units of which is = to 0.10 rate = Dnpoid 0.08- 1) Determine the average rate of product formation between 50 and 150 seconds. H90'0 0.04 2) Is the tangential slope positive or negative for: 0.02- - Product? reactant Reactant? 150 00, 250 Time (s) The at a single time is the rate. The slope over a range of time is the rate. Connection to Mathematics & Physics Slope is the rate of change. The symbol (delta) means "for a range (average rate of change). Example: A car decreases speed from 35 m/s to 15 m/s over a period of 5 seconds. What is the car's acceleration (average rate of change for velocity)? Example: The concentration of CHaF product increases from 0.20 mol/L to 0.80 mol/L over 12 seconds of reaction time. Determine the average reaction rate for this time. CH4 + F2 CH3F + HF
