What information does an energy diagram give?
A. It shows the rate of the reaction as a function of time.
B. It shows the transfer of potential energy to kinetic energy.
C. It shows the energy requirements needed in order for a reaction to occur.
D. It shows how concentrations of reactants affect the energy.
Answer (2)
An energy diagram illustrates the energy changes during a chemical reaction, showing the energies of reactants and products and the activation energy required. It helps to understand whether a reaction is exothermic or endothermic. Therefore, option C, which mentions energy requirements for a reaction, is the correct choice. ;
An energy diagram shows energy changes during a chemical reaction, including the activation energy needed. It helps to identify whether a reaction is exothermic or endothermic based on energy levels of reactants and products. The correct choice is C , as it indicates the energy requirements necessary for a reaction to occur.
