Considering the collision of molecules that collide with i2 h2 and b. Had the opportunity to form a reactive, rather than because the direction of the collision of two molecules, as appropriate.
When considering collision of H2 molecules with I2 found that collision. ข. reaction is likely to have more than a g because of the direction in the collision of two molecules.
When you consider the collision of molecules H I 2 to 2 found that the crash-B. There is an opportunity to have more than a chemical reaction occurs in direction due to the collision of the two molecules of the appropriate
