WebAug 13, 2024 · However, endothermic reactions do occur spontaneously, or naturally. There must be another driving force besides enthalpy change which helps promote spontaneous chemical reaction. Entropy as a Driving Force A very simple endothermic process is that of a melting ice cube. WebReactions tend to go faster with higher temperature, up to a point, beyond which their rate drops sharply as their enzymes denature. Each species has its own network of metabolic …
WebIn general, the transition state of a reaction is always at a higher energy level than the reactants or products, such that E A \text E_{\text A} E A start text, E, end text, start subscript, start text, A, end text, end subscript always has a positive value – independent of whether the reaction is endergonic or exergonic overall. The activation energy shown in … WebPour ½ cup of tap water into a cup. 2. Stir the cup with a thermometer and record the temperature. 3. Add four teaspoons of sodium bicarbonate to the water and stir with the thermometer. Record the resulting temperature. 4. Subtract the temperature from Step 2 from the temperature in Step 3. This will give you the change in temperature.
