WebMar 25, 2010 · How did the change in temperature affect the reacting molecules? a) The average velocity of the molecules doubled. b) average energy of the molecules doubled. c) the number of collisions per second doubled. d) the number of molecules above the reaction energy threshold doubled. Please explain me in detail to support your answer. WebFeb 12, 2024 · When molecules collide, the kinetic energy of the molecules can be used to stretch, bend, and ultimately break bonds, leading to chemical reactions. If molecules move too slowly with little kinetic energy, or collide with improper orientation, they do not react and simply bounce off each other.
WebThe first step in the gas-phase reaction between carbon monoxide and oxygen is a collision between the two molecules: CO ( g) + O 2 ( g) CO 2 ( g) + O ( g) Although there are many different possible orientations the two molecules can have relative to each other, consider the two presented in Figure 12.13. WebApr 15, 2024 · A new mechanically stimulated solid-state reaction of PtCl4 with sodium β-diketonates has been discovered. Platinum (II) β-diketonates were obtained by grinding excess sodium trifluoroacetylacetonate Na(tfac) or hexafluoroacetylacetonate Na(hfac) in a vibration ball mill, followed by subsequent heating of the resulting mixture. The reactions …
WebThe collision theory states that for a chemical reaction to happen, the reactant molecules have to collide in the right orientation and with enough energy to react and form a product. This means that more collisions lead to a faster reaction.
