What would happen to the rate of a reaction with rate law rate k NO2H2 if the concentration of NO were doubled?
The rate would be four times larger.
Rates of reaction can be expressed depending upon their order. For example say you have a reaction between two chemicals and the initial rate for that reaction is known :- when:- The concentration of one of the reactants is doubled and the other reactants concentration remains the same and the overall rate of reaction does not change - reaction is zero order with respect to chemical which was doubled. The concentration of one of the…
What is the order of reaction if the half life of a reaction is halved as the initial concentration of the reactant is doubled.?
Second order. If the half life of a reaction is halved as the initial concentration of the reactant is doubled, it means that half life is inversely proportional to initial concentration for this reaction. The only half life equation that fits this is the one for a second-order reaction. t(1/2) = 1/[Ao]k As you can see since k remains constant, if you double [Ao], you will cause t(1/2) to be halved.
Why is a chemical reaction rate doubled when the concentration of one reactant is doubled explain this in terms of collision theory?
What is the effect on km and Vmax of an enzyme catalysed reaction if enzyme concentration is doubled?
As enzyme concentration increases the more active sites there are avalible, so the rate of reaction increases. therefore the turnover number increases. Hope it helped! Tasha The above it not true. The turn over number is Vmax/Et so if the enzyme concentration is doubled the velocity will also be doubled. Therefore the turn over number will remain constnat.
Why was there no increase in the reaction rate with 8.0g. of substrate compared to 4.0g. of substrate?
because the amount of the other variables are the same, no change. once 4.0 g of lactose substrate or whatever it is is at it's maximum reaction rate, it can do no one reaction therefore there was no reaction in the 8.0 g of substrate. Because the reaction volume was also doubled; so there was no change in concentration of substrate.
What would happen to the rate of a reaction with rate law rate k no 2 h2 if the concentration of h2 were halved-?
What would happen to the rate of a reaction with rate law rate kNO2H2 if the concentration of NO were double?
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 is the relation between an concentration of an reactants and the products which it is in an state of equilibrium?
The rate(speed) of a reaction is directly related to the concentration of the enzyme. As the concentration of the enzyme increases, the speed of a reaction will increase. This is because the more concentrated the enzyme concentration, the more particles there are to collide and react. There will be a stronger concentration of enzyme to react with the substrate.
