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...
