The helium balloon which has more collisions at room temperature between a 1 L helium balloons at 0.1 atm or a 1 L helium balloon at 455 mmHg is to be determined. Concept introduction: According to kinetic molecular theory postulates, Particles present in the gas have consistent and random motion. They collide with each other or the walls of their container and these collisions are elastic in nature. The average kinetic energy of every gas particles is directly related to temperature. The speed of gas molecules increases with increase in temperature. Molecules having low molar mass will move faster than the molecules with high molar mass. When gas molecules collide with each other or the walls of their container, pressure is also exerted. It happens due to the velocity by which molecules collides with each other. To determine: The helium balloon which has more collisions at room temperature.

Heating an alcohol in the presence of sulfuric or phosphoric acid will cause a dehydration to occur: the removal of the elements of water from a molecule, forming an alkene. The reaction usually follows an E1 mechanism. The SN1 pathway is suppressed by using a strong acid whose conjugate base is a poor nucleophile. Further, heating the reaction mixture causes a greater increase in the rate of E1 compared to the rate of Sy1. 3rd attempt h Draw curved arrow(s) to show how the alcohol reacts with phosphoric acid.
