An industrial chemical reaction has a rate law: rate = k [C]. The activation energy for the reaction is 3.0000 x 10^4 J/mol and A = 2.000 x 10^-3. What must be the reaction temperature if a rate of 1.000 x 10^-9 M/s is required and [C] must be kept at 0.03000M. What must be the value of k to achieve the necessary rate?
propane reacts with oxygen in the air to produce carbon dioxide and water. In a particular experiment, 38.0 grams of carbon dioxide are produced from the reaction of 22.05 grams of propane with excess oxygen.
