Rate constants are temperature dependent. Therefore, the reactions must all be conducted at the same temperature in order for the linear relation derived above to be correct. Thus, another source of error in these experiments is any temperature difference between reaction flasks. Refer to the Introduction section where the identity of the rate-determining reaction was discussed. Suppose that the rate constant for reaction (1a) increases by 2% for each increase of 1 °C, and the rate constant for reaction (1b) increases by 20% for each increase of 1 °C. Q. What would be the percent decrease in the observed elapsed time when the temperature increases by 1 °C? 2% 20% O 2 + 20 = 22% 0.02 × 20 = 0.4%

(2) The reaction-rate data given below were obtained using a batch reaction system for the reaction A→products. Plot the data in appropriate form to test the fit for zero- and first-order kinetics. From the plot that gives the best fit, determine the appropriate reaction rate constant (remember the units). Time, min CA, (g/m3) 0 30 0.5 25.4 1 21.6 2 16.9 4 13.1 8 8.3 16 3.2 32 0.31
Hypothetically, the reaction H2 + 2IC1→ I2+ 2HC1 is first order in [H2] and second order in [ICI]. Based on the first fast step given below and the fact that the second step is the slow step, propose a second-step mechanism, and show that it conforms to the experimentally determined reaction order. Assume that [I2] does not affect the reaction rate. H2 + 2ICI → I2 + 2HC1 Fast: 2ICI → I2 + 2Cl Slow:

The starting concentration (time zero) of crystal violet is 1 x 10-4 M. Using the proper integrated rate law and the calculated value for k, calculate the concentration of crystal violet after 240 seconds. Look at the equation of the trend line for your lost linear graph and the beer-lambert law. Equation from graph from NaOH 0.0660M is y= -0.0105x-0.6277
There are several factors that affect the rate of a reaction. These factors include temperature, activation energy, steric factors (orientation), and also collision frequency, which changes with concentration and phase. All the factors that affect reaction rate can be summarized in an equation called the Arrhenius equation: KA-E/RT where is the rate constant, A is the frequency factor, Ea is the activation energy, R = 8.314 J mol-¹ K-¹ is the gas constant, and T is the absolute temperature.
