Start with a simpler problem - what happens to the reaction rate when the concentration of nitrogen oxide is doubled?
The reaction rate of NO & O2 to form NO2 is determined by the rate law, which is a mathematical expression that relates the concentration of the reactants to the rate of the reaction. It is influenced by factors such as temperature, concentration, and the presence of a catalyst.
An increase in temperature generally leads to an increase in the reaction rate, as molecules have more kinetic energy and are able to collide more frequently and with greater force. However, at extremely high temperatures, the reaction may start to slow down due to the breakdown of some of the reactant molecules.
The concentration of the reactants affects the reaction rate by determining the number of collisions that can occur between the molecules. A higher concentration of reactants leads to a higher number of collisions, which can increase the reaction rate. However, if the concentration of one reactant is significantly higher than the other, it may become the limiting factor in the reaction.
A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the reaction itself. In the case of the reaction between NO and O2 to form NO2, a catalyst can provide an alternate pathway with a lower activation energy, making it easier for the reaction to occur. This can greatly increase the reaction rate.
The reaction rate can be measured by monitoring the change in concentration of either the reactants or the products over time. This can be done using various techniques such as spectrophotometry or titration. The initial rate of the reaction can also be determined by measuring the slope of the concentration vs. time graph at the beginning of the reaction.
