Slowly forms a surface oxide at room temperature Very slow reaction. WebA. the rate remains the sameB. the rate decreases by a factor of 2C. the rate increases by a factor of 2D. the rate increases by a factor of 4 A C. the rate increases by a factor of 2 8 Q The reaction of 1-bromopropane with sodium iodide gives 1-iodopropane. What is the effect of doubling the concentration of NaI on the rate of the reaction?
WebReaction rate increases with concentration, as described by the rate law and explained by collision theory. As reactant concentration increases, the frequency of collision increases. The rate of gaseous reactions increases with pressure, which is, in fact, equivalent to an increase in the concentration of the gas. WebExpert Answer 100% (108 ratings) SN2 reaction is a bimolecular nucleophilic reaction. the rate expression for an SN2 reaction is given as: R-X + B: ------> R-B + X- where, R-X is an alkyl halide (substrate) B: is the nucleophile X- is the leaving group R-B is the product rate =k [ … View the full answer Transcribed image text:
WebAug 17, 2024 · In chemistry, reactivity is a measure of how readily a substance undergoes a chemical reaction. The reaction can involve the substance on its own or with other atoms or compounds, generally accompanied by a release of energy. The most reactive elements and compounds may ignite spontaneously or explosively. WebRates usually increase when the concentration of one or more of the reactants increases. For example, calcium carbonate (CaCO 3) deteriorates as a result of its reaction with the pollutant sulfur dioxide. The rate of this reaction depends on the amount of sulfur dioxide in the air (). An acidic oxide, sulfur dioxide combines with water vapor in ...
WebAtoms must be close together to form chemical bonds. This simple premise is the basis for a very powerful theory that explains many observations regarding chemical kinetics, including factors affecting reaction rates. Collision theory is based on the following postulates: The rate of a reaction is proportional to the rate of reactant collisions ...
