In order for a reaction to occur, particles must ______ in the proper _____ .
What are the 2 words would be correctly fill in the blank?
Thanks
In order for a reaction to occur, particles must collide in the proper orientation.
The two words that would correctly fill in the blanks are "collide" and "orientation".
In order for a chemical reaction to occur, particles must collide with each other. Collisions between particles provide the necessary energy for the reaction to take place. However, simply colliding is not enough for a reaction to occur. The particles must also have the proper orientation or arrangement. This means that they must be aligned in a specific way so that the necessary chemical bonds can be formed or broken.
To determine the correct answer to this question, you can think about what is required for a chemical reaction to happen. You might know that collisions are essential, as they provide the necessary energy for the reaction to proceed. Additionally, considering that reactions involve the rearrangement of atoms, it is logical to conclude that the particles must have the proper orientation or arrangement for the reaction to take place. Therefore, "collide" and "orientation" are the correct answers.
