Is free energy of cell reaction positive when emf of cell reaction is positive?
No, the free energy of a cell reaction is negative when the emf of the cell reaction is positive. This is because a positive emf indicates that the reaction is spontaneous and capable of performing work, resulting in a negative change in free energy.
How would you compare the formation of positive ions with the formation of negative ions in terms of energy changes?
The formation of positive ions typically requires energy input in the form of ionization energy to remove electrons, whereas the formation of negative ions releases energy in the form of electron affinity when electrons are added. Positive ions have higher potential energy compared to their neutral atoms, whereas negative ions have lower potential energy. Overall, the energy changes involved in forming positive and negative ions are opposite in nature.
What does it indicate when the value of G is negative in a chemical reaction?
When the value of G is negative in a chemical reaction, it indicates that the reaction is spontaneous and releases energy.
Where is the energy which is released during a chemical reaction stored to begin with?
The energy released during a chemical reaction is stored in the chemical bonds of the reactant molecules before the reaction occurs. During the reaction, these bonds are broken, and new bonds are formed, releasing the stored energy in the process.
What does a negative enthalpy indicate in a chemical reaction?
A negative enthalpy in a chemical reaction indicates that the reaction is exothermic, meaning it releases heat energy to the surroundings.
What are the negative and positive effects of mechanical energy?
Negative effects of mechanical energy include the potential for injuries if not properly controlled or harnessed. Positive effects include the ability to perform work efficiently and power various machines that improve daily life and productivity.
Does energy flow positive to negative or negative to positive with magnets?
positive to a negative
What are some positive and negative effects of geothermal energy?
Positive effects of geothermal energy include being a renewable energy source that produces low greenhouse gas emissions and has a reliable power generation. Negative effects can include the potential for land subsidence, induced seismic activity, and the release of hydrogen sulfide and other gases during operation.
Does energy flow through the negative or positive of a battery?
Energy flows from the negative terminal to the positive terminal of a battery.
What type of stored energy does a battery contain?
A battery stores chemical energy that is converted into electrical energy when needed. This chemical energy is generated through the reaction between the battery's positive and negative electrodes.
Differentiate a positive catalyst from a negative catalyst?
A positive catalyst is a catalyst which speeds up the rate of a chemical reaction by lowering its activation energy. A negative catalysts slows the rate of a chemical reaction or makes it less likely to occur.
What are two positive and two negative effects of India's great river?
two positive (1) they get water (2) they can get energy from flowing water negative (2) it is polluted (1) it is far distances from their homes
What are two positive and two negative effects of India and great rivers?

How do the battery separate the negative energy and the positive energy?
Batteries separate negative and positive energy using chemical reactions that occur within the battery. The negative energy is stored in the anode (typically made of a metal like zinc) and the positive energy is stored in the cathode (often made of a material like manganese dioxide). When the battery discharges, electrons flow from the negative terminal (anode) to the positive terminal (cathode), creating an electrical current.
What is the difference between positive catalyst and negative catalyst?
The substances which increase the rate of a chemical reaction are called a Positive Catalyst whereas The substances which decrease the rate of a chemical reaction are called Negative Catalyst. Positive Catalyst decreases the Activation energy of reactant molecules whereas negative catalyst increases the Activation energy of the reactant molecules. Positive Catalyst is also called the Promoter whereas negative catalyst is also called Inhibitor.
