<u>Answer:</u> The correct answer is Option 4: U
<u>Explanation:</u>
Activation energy is defined as the energy that is given to a chemical system with potential reactants to produce products. It is represented as
It is represented as the energy from the reactants to the activated complex.
Reverse reaction is defined as the reaction in which the products formed become reactants and leads to the formation of reactants back.
So, here, the activation energy of the reverse reaction is the energy between the products and the activated complex, which is represented as letter U in the given graph.
Hence, the correct answer is Option 4: U
Answer : The correct answer is 109.
Explanation :
Significant figure : It is defined as the each digits of a number have meaning or contribute to the value of the number.
The addition of given digits is,
43.2 + 50.0 + 16.0 = 109.2
As per the question, the given digits has 3 significant figures. But the answer after addition is 109.2 has 4 significant figures.
The addition rule of significant rule is the least precise number of significant figure in any number of the problem determines the number of significant figures in the answer.
Therefore, from the addition rule, the correct answer is 109.
