ln(k) = -E_a/R 1/T + ln(A) A plot of ln (k)versus 1/T result in a straight line with a slope = -E_a/R. The value of E_a can then be calculated using the value of R and to the slope of the line. This experiment uses the Arrhenius equation, which relates the temperature and specific reaction rate constant to determine the activation energy for the crystal violet reaction. The reaction will be performed at different temperatures. Once the order of reaction...

A certain first-order reaction has a rate constant of 1.65 min-1 at 20°C. What is the value of the rate constant at 60°C if the activation energy is 75.5 kJ/mol? The rate constant is 105 times bigger at 300 K than at 200K. Explain why reaction rate increases with temperature? At 227°C, the reaction: SO2Cl2(g) SO2(g) + Cl2(g), has an equilibrium constant of KC = 2.99×10-7. If a reaction mixture initially contains 0.175 M SO2Cl2, what is the equilibrium concentration...
