Vegetable and fruit juices are ideal for bland diets. Fresh fruits, such as oranges, bananas, grapefruits and peaches are healthful choices. Most canned fruits and vegetables are also safe. Those known to cause digestive issues, such as grapes, prunes or dates, are not recommended for a bland diet.
: an equation describing the mathematical relationship between temperature and the rate of a chemical reaction Note: The Arrhenius equation is sometimes expressed as k = Ae-E/RT where k is the rate of chemical reaction, A is a constant depending on the chemicals involved, E is the activation energy, R is the universal gas constant, and T is the temperature.
R is the universal gas constant. 1 (at T 1) to k 2 (at T 2), take the ratio of the Arrhenius equations for each of the two temperatures: The calculator below solves this equation for the activation energy, given a rate factor increase (k 2 /k 1) and an initial and final temperature.Use it to evaluate the rule of thumb. Try answering the following questions: 2 /Cl 2 mixture will at first elevate the reaction rate only slightly...then the activation energy must be Ea =. kJ/mol. If the activation energy has a particular value, and if the temperature change occurs in the right range, and if the reaction is an elementary one that obeys the Arrhenius equation, then a 10Â°C rise might double the reaction rate. It's a very iffy generalization.
