Answer
The blanks in the question should be filled as follows: For a chemical reaction to take place, the reactants must have the 'activation energy'. This is the 'minimum' amount of energy needed for particles to 'react'.
Explanation
## Step 1:The question is asking why wood needs to be ignited by a flame to burn, even though the process of burning wood is energetically favorable. The answer lies in the concept of activation energy. ## Step 2:In chemistry, for a reaction to occur, the reactants must possess a certain minimum amount of energy. This minimum energy is called activation energy. ## Step 3:Activation energy is the energy barrier that must be overcome for reactants to form products. It is the energy needed for particles to react.
