What effect temperature have on reaction rate?
An increase in temperature speeds up the reaction rate.
How is the effect of a concentration changes on the reaction rate seen in the rate law?
In the rate law, the reaction rate is expressed as a function of the concentrations of the reactants, each raised to a power corresponding to its reaction order. When the concentration of a reactant increases, the reaction rate typically increases as well, reflecting a direct relationship for first-order reactions. For higher-order reactions, the effect can be more pronounced; for example, doubling the concentration of a second-order reactant quadruples the reaction rate. Thus, the rate law quantitatively captures how changes in concentration influence the speed of the reaction.
What would happen to the rate of a reaction with rate law rate k NO2H2 if NO were halved?
In the rate law given as rate = k[NO2][H2], the concentration of NO does not appear, so the rate of the reaction is independent of its concentration. Therefore, if the concentration of NO were halved, it would have no effect on the rate of the reaction. The reaction rate would remain unchanged as long as the concentrations of NO2 and H2 remain constant.
How are the concentration of the reactants and reaction rate related?
rate laws a+the higher the concentration = more particles = higher chance of a collision happening = higher/faster reaction rate
What effect does a catalyst have?
A catalyst speeds up a chemical reaction by lowering the activation energy required for the reaction to occur. It does so by providing an alternative reaction pathway that requires less energy to initiate the reaction. The catalyst itself remains unchanged at the end of the reaction and can be used over and over again.
What effect does the concentration of reactants have on the rate of reaction?
increasing the concentration increases the rate of the reaction
What effect does the concentrate of reactants have on the rate of a reaction?
increasing the concentration increases the rate of the reaction

What effect does the concentration on reactants have on the rate of a reaction?
increasing the concentration increases the rate of the reaction
What effect of concentration of reactants have on the rate of a reaction?
increasing the concentration increases the rate of the reaction
What effect does the concentration of reactants have on the rate of speed?
The effect of concentration of reactants on rate of reaction depends on the ORDER of the reaction. For many reactions, as the concentration of reactants increases, the rate of reaction increases. There are exceptions however, for example a zero order reaction where the rate of reaction does not change with a change in the concentration of a reactant.
What effect does catalyst on a reaction?
A catalyst speeds up the rate of a reaction.
What effect does a catalyst having a reaction?
A catalyst speeds up the rate of a reaction.
