How To Determine The Initial Rate Of Reaction From A Graph Jul 12 2023 nbsp 0183 32 To experimentally determine the initial rate an experimenter must bring the reagents together and measure the reaction rate as quickly as possible If this is not possible the experimenter can find the initial rate graphically
Jan 3 2025 nbsp 0183 32 Initial Rates Methods The initial rates method determines the rate at the very start of the reaction when t 0 The initial rate can be found by Drawing a concentration time graph Adding a tangent at t 0 Calculating the gradient of the tangent One example of measuring the initial rate could be the reaction of calcium carbonate with Nov 21 2019 nbsp 0183 32 In this video I will teach you how to calculate the initial rate of reaction from a graph quickly and easily using the tangent method This is a required ski

Oct 16 2024 nbsp 0183 32 Using this graph calculate the initial rate of reaction Step 1 Estimate the extrapolated curve of the graph Step 2 Find the tangent to the curve at 0 seconds the start of the reaction Oct 25 2024 nbsp 0183 32 From each graph the initial rate is calculated by drawing a tangent to the line at t 0 and calculating the gradient The gradient at t 0 is the initial rate for that reaction General Example Let s take the following general reaction as an example 2A B C C D
Calculating rate of reaction at the initial rate The rate at the start of the reaction can be calculated by drawing a tangent to the curve at time 0 and finding the gradient of the tangent Drawing a tangent The tangent is a straight line which touches the curve at the point of interest only Jun 9 2015 nbsp 0183 32 To determine this without curve fitting data pairs or linearizing the plot it suffices to see if the half life mathrm t 1 2 is constant From the photo of the graph the initial concentration declines to mathrm 0 2 M at about mathrm t 13 s
