- What happens to the reactants in an ineffective molecular collision?arrow_forwardThe equilibrium constant expression for a given reaction depends on how the equilibrium equation is written. Explain the meaning of that statement. You may, if you wish, use the equilibrium equation N2(g)+3H2(g)2NH3(g) to illustrate your explanation.arrow_forwardConsider the following reactions: H2(g)+I2(g)2HI(g)andH2(g)+I2(s)2HI(g) List two property differences between these two reactions that relate to equilibrium.arrow_forward
- When writing a chemical equation for a reaction that comes to equilibrium. how do we indicate symbolically that the reaction is reversible?arrow_forwardOld-fashioned smelling salts consist of ammonium carbonate, (NH4)2CO3. The reaction for the decomposition of ammonium carbonate (NH4)2CO3(s)2NH3(g)+CO(g)+H2O(g) is endothermic. Would the smell of ammonia increase or decrease as the temperature is increased?arrow_forward. Account for the increase in reaction rate brought about by a catalyst.arrow_forward
- use the kineticmolecular theory to explain why an increase in temperature increases reaction rate.arrow_forwardSubstances that poison a catalyst pose a major concern for many engineering designs, including those for catalytic converters. One design option is to add materials that react with potential poisons before they reach the catalyst. Among the commonly encountered catalyst poisons are silicon and phosphorus, which typically form phosphate or silicate ions in the oxidizing environment of an engine. Group 2 elements are added to the catalyst to react with these contaminants before they reach the working portion of the catalytic converter. If estimates show that a catalytic converter will be exposed to 625 g of silicon during its lifetime, what mass of beryllium would need to be included in the design?arrow_forwarda What happens to a reaction rate as temperature drops? Give two explanations for the change. State which one is more important and explain why. b How does a catalyst affect reaction rates? c Compare reaction rates when a given reactant concentration is high with the rate when the concentration is low. Explain the difference.arrow_forward
- By which of the following mechanisms does a catalyst operate? a. It decreases the activation energy barrier for a reaction. b. It serves as a reactant and is consumed. c. It increases the temperature of a reaction. d. It increases the concentration of reactants.arrow_forwardThe following series of diagrams represent the reaction XY followed over a period of time. The X molecules are red and the Y molecules are green. At the end of the time period depicted, has the reaction system reached equilibrium?
