In a decompostion reaction, the reaction decays 23.4 times more rapidly at 23°C then at 4 °C. What is the overall activation energy (kJ/mol) of the process? Enter your answer as an integer.
Food deteriorates more slowly in a refrigerator because
3. Food deteriorates more slowly in a refrigerator because (10.1) A. more reactants are added B. products are removed C. the energy of activation is higher D. fewer collisions have the energy of activation E. collisions have the wrong orientation upon impact 4. A reaction reaches equilibrium when (10.2) A. the rate of the forward reaction is faster than the rate of the reverse reaction B. the rate of the reverse reaction is faster than the rate of the forward reaction C. the concentrations of reactants and products are...

A food Calorie is a unit of energy equal to about 4184J. When you consume a 100 Calorie doughnut, that energy is stored in your body unless you use it (conservation of energy, folks). (a) How much work do you do when you lift yourself (assume m “ 80kg) up one stair? Note: The typical stair in the US is about 18cm. (b) How many times do you need to walk up the Exorcist stairs (about 80 stairs) to work...

In terms of saving energy, bicycling and walking are far more efficient means of transportation than is travel by automobile. For example, when riding at 14.5 mi/h, a cyclist uses food energy at a rate of about 400 kcal/h above what he would use if he were merely sitting still. (In exercise physiology, power is often measured in kcal/h rather than in watts. Here, 1 kcal = 1 nutritionist's Calorie = 4, 186 J.) Walking at 2.72 mi/h requires about...

Tesco-Case Study Tesco is the UK’s largest food retailer, with a sales turnover of more than 67.5 billion. While it has some 638 stores in central Europe, and some 636 in the Far East, most are in the United Kingdom and Northern Ireland, where it has nearly 1,800. This number has increased rapidly as Tesco entered the convenience store market with deals such as the Tesco Express alliance with Esso to run grocery shops at petrol stations. The product range...

People gain weight when they take in more energy from food than they expend. Some researchers wanted to investigate the link between obesity and energy spent on daily activity. Choose 20 healthy volunteers who don't exercise. Deliberately choose 10 who are lean and 10 who are mildly obese but still healthy. Attach sensors that monitor the subjects' every move for 10 days. The table below presents data on the time (in minutes per day) that the subjects spent standing or...
