Compared to trial 1, trial 2, reactant molecule collisions occur more frequently.
If the two molecules A and B are to interact, they must get close enough to each other that some of their current bonds will be broken and space will be left for any new bonds that will be required for the end products to form. A collision is the name given to such a meeting.
The collision theory postulates that the molecules of reactants are hard spheres, and that reactions can only take place when these spheres (molecules) clash with one another.
According to the collision theory, for a reaction to take place, the particles involved must collide the proper way around (with the correct orientation) and with sufficient force to cause the bonds between the reactants to be broken.
The complete question is : 2NO(g)+2H2(g)→N2(g)+2H2O(g)
The information in the data table above represents two different trials for an experiment to study the rate of the reaction between NO(g) and H2(g), as represented by the balanced equation above the table. Which of the following statements provides the correct explanation for why the initial rate of formation of N2 is greater in trial 2 than in trial 1 ? Assume that each trial is carried out at the same constant temperature.
