Answer: The reaction is exothermic reaction as the energy of products is less than the energy of reactants.
Explanation: Exothermic reactions are defined as the reactions in which energy of the product is less than the energy of the reactants. The total energy is released in the form of heat and for the reaction comes out to be negative.
Labeling of the parts in the diagram:
A represents the activation energy which is the energy required by reactants to cross the energy barrier to get converted to products.
E represents the potential energy of the reactants.
B represents the activated complex.
D represents the potential energy of the products.
C represents the total enthalpy change of the reaction, which comes out to be negative for exothermic reactions.
Answer:
used to date rocks and other objects based on the known decay rate of radioactive isotopes.
Explanation:
Different methods of radiometric dating can be used to estimate the age of a variety of natural and even man-made materials.
In order to identify the reducing agent let us check the oxidation states
I2 + Ti+4 ----> Ti + IO3- reducing agent
I2 : oxidation state of I = 0
Ti^+4 = oxidation state of Ti = +4
Ti : oxidation state = 0
IO3^-1 , oxidation state of Iodine = +5
So here the Ti undergoes reduction hence it is oxidizing agent
Where iodine undergoes oxidation hence it is reducing agent
