What Affects the Rate of Reaction?
and The rate, rate = k[A]2[B]2, What is the rate law for this reaction? Express the rate law symbolically in terms of ''k'', [[A], and [[B]. Consider the reaction A + 2B → C whose rate at 25° C was measured using three different sets of ini...
Therefore, heating the reaction mixture increases the number of effective collisions between reactant particles, thus increasing the rate of the forward reaction. 加热反应混合物会增加反应物粒子的平均动能,使更多粒子拥有足够的能量克服活化能,从而发生有效碰撞,进而提高正向反应速率。
There are many parameters that influence how quickly reactions take place. Some can be very fast, such as during chemical explosions, and some can take millions of years, such as the the radioactive decay of uranium to lead. How fast things happen is referred to as the rate of reaction....
解析 (particles) have more energy OR (particles) move faster more collisions per second OR greater collision rate more (of the) particles OR collision have sufficient energy activation energy to react OR a greater percentage proportion fraction of collision are successful ...

The slope of the tangent at a point on the curve of concentration of a reactant as a function of time gives the instantaneous rate of reaction. View Solution For a reaction, the instantaneous rate of reaction with respect to x, y and z is expressed as r=−12Δ[x]Δt=−13Δ[y]...
