The rate of the reaction begins to decrease as reactants are used up (apex)
What happens to the reaction rate as the reactants get used up in the reaction?
The rate of the reaction begins to decrease as reactants are used up (apex)
Why does a catalyst speed up the rate of reaction?
The use of a catalyst increases the chance of particles meeting. This causes there to be a decrease in activation energy, and results in an increase in rate of reaction.
In a first-order reaction how does the rate change if the concentration of the reactant decreases to one-third its original value?
In a first-order reaction, the rate of reaction is directly proportional to the concentration of the reactant. If the concentration decreases to one-third of its original value, the rate of the reaction will also decrease to one-third. This is because the rate equation for a first-order reaction can be expressed as ( \text{Rate} = k[A] ), where ( k ) is the rate constant and ([A]) is the concentration of the reactant. Therefore, a decrease in concentration leads to a proportional decrease in the reaction rate.
What would happen to the rate of a reaction with rate law rate k NO 2 H2 if the concentration of NO were halved?
If the concentration of NO is halved, the rate of the reaction will also be halved. This is because the rate of the reaction is directly proportional to the concentration of NO raised to the power of its coefficient in the rate law (in this case 1). So, halving the concentration of NO will result in a proportional decrease in the rate of the reaction.
A material used to decrease the rate of a chemical reaction is what?
retardant
A material used to decrease the rate of a reaction is called?
inhibitor
What would happen to the rate of a reaction with rate law rate k NO 2 H2 if the concentration of H2 were halved?
Halving the concentration of H2 will decrease the rate of the reaction, assuming it is a first-order reaction with respect to H2. Since the rate law is rate = k[NO]^2[H2], cutting the concentration of H2 in half will decrease the rate of the reaction by a factor of 0.5.
What would most likely result in the greatest decrease in the rate of a chemical reaction?
Decreasing the temperature or changing the concentration of the reactants would most likely result in the greatest decrease in the rate of a chemical reaction. These changes affect the collision frequency and energy of the reacting molecules, slowing down the overall reaction rate.
