Which type of reaction are characteristic or negative heat flow?

Reactions that are characteristic of negative heat flow are exothermic reactions. In these reactions, energy is released to the surroundings, usually in the form of heat, resulting in a decrease in the system's internal energy. Common examples include combustion and respiration, where bonds are broken and formed, releasing energy. The release of heat often leads to an increase in the temperature of the surroundings.


If the heat of reaction is negative the reaction is a?

If the heat of reaction is negative, the reaction is exothermic. This means that the reaction releases energy, usually in the form of heat, to the surroundings. As a result, the temperature of the surroundings may increase, and the products of the reaction have lower energy than the reactants.


What does a negative delta H for a reaction suggest?

A negative delta H for a reaction suggests that the reaction is exothermic, meaning it releases heat to its surroundings. This implies that the products of the reaction have lower energy than the reactants.


What type if reaction has a positive heat flow?

A reaction with a positive heat flow is called an endothermic reaction. In this type of reaction, energy is absorbed from the surroundings, resulting in a decrease in temperature of the surroundings. Common examples include photosynthesis and the dissolution of certain salts in water. During these reactions, the products have higher energy than the reactants due to the absorbed heat.


What is the heat of reaction A what is the heat of reaction B?

The heat of reaction, also known as enthalpy change, is the amount of energy released or absorbed during a chemical reaction at constant pressure. For reaction A, the heat of reaction would be the specific enthalpy change associated with that reaction, while reaction B would have its own distinct heat of reaction based on the reactants and products involved. These values can be positive (endothermic) or negative (exothermic) depending on whether the reaction absorbs or releases heat, respectively. To provide exact values, the specific reactions and their thermodynamic data would be needed.

Is the reaction endothermic or exothermic, and what is the enthalpy of the reaction?

The reaction is exothermic, meaning it releases heat. The enthalpy of the reaction is negative, indicating that it is exothermic.


What relates qrxn and qsur?

The relationship between qrxn (heat of reaction) and qsur (heat of surrounding) is described by the first law of thermodynamics, which states that the heat released or absorbed by a reaction is equal and opposite to the heat gained or lost by the surrounding environment. In an exothermic reaction, qrxn is negative and qsur is positive as heat is released to the surroundings. In an endothermic reaction, qrxn is positive and qsur is negative as heat is absorbed from the surroundings.
