When the concentration of A is doubled the rate for the reaction 2a B?

When the concentration of A is doubled the rate for the reaction 2a B?

When the concentration of A is doubled, the rate for the reaction: 2 A + B → 2 C quadruples. When the concentration of B is doubled the rate remains the same.

What is the change of the rate of the reaction 2a B a2b if the concentration of A is cut in half and the concentration of B is increased in 2 times?

Hi, Answer: The rate of reaction will changes 2 times.

What will happen to the reaction rate if the concentration of A is doubled?

The rate is proportional to the concentration of a reactant. When you double the concentration the rate doubles. The rate is proportional to the square of the concentration of a reactant. When you double the concentration the rate goes up four times.

How will the rate change if the concentration of A is doubled and the concentration of B is halved?

The rate is directly proportional to the concentration. If you double the concentration, you double the rate. If you triple the concentration, you triple the rate. If you halve the concentration, you halve the rate, and so on.

When the concentration of B is doubled the rate remains the same?

Reaction Rate And Rate Law : Example Question #3 When the concentration of A stays the same but the concentration of B doubles, the rate quadruples, showing a second order rate law based on B. When the concentration of A doubles and B stays the same, the rate also doubles, showing a first order rate law based on A.

What is the Molecularity of the reaction 2A → B?

∴O. =2+1=3 and molecularity is 3[2A+B]. …

When the rate of reaction is equal to the rate constant?

If the rate of the reaction is equal to the rate constant , the order of the reaction is. For zero order reaction r = k .

When the rate of the reaction is equal to rate constant the order of the reaction is?

zero order reaction
when the reaction is a zero order reaction.

What is the rate constant for the reaction 2A B → C?

The rate equation for the reactions 2A + B to C is found to be: rate = k[A][B]. The correct statement in relation to this reaction is that the. t1/2 is a constant. value of k is independent of the initial concentration of A and B.

When A is doubled and B is held constant the initial rate of reaction will not change?

For Rate = k [B]2, doubling [A] will not change the rate, and holding [B] constant will not affect the rate, so the rate does not change.

When initial concentration of the reactant is doubled?

– According to the question, the initial concentration of the reactant is doubled and we have to find out the new half life of the zero order reaction. Hence we can say that after doubling the concentration of the reactant, the half life period of this zero order reaction will be doubled.

What is the Order of the equation 2A + B2C?

3. For a reaction 2A + B 2C, with the rate equation: Rate = k [A] 2 [B] (a) the order with respect to A is 1 and the order overall is 1. (b) the order with respect to A is 2 and the order overall is 2.

What happens when the concentration of reactant molecules is increased?

When the concentration of reactant molecules is increased, the rate of reaction increases. The best explanation is: As the reactant concentration increases, (a) the average kinetic energy of molecules increases. (b) the frequency of molecular collisions increases. (c) the rate constant increases.

Which reaction will obey the rate law at 300 K?

At 300 K, the following reaction is found to obey the rate law: Rate = k [NOCl] 2 : 2NOCl 2NO + Cl 2 Consider the three postulated mechanisms given below. Then choose the response that lists all those that are possibly correct and no others. (a) 2, 3 (b) 3 (c) 1 (d) 2 16. A correct reaction mechanism for a given reaction usually is:

How is the concentration stress of a reactant relieved?

The concentration stress of an added reactant/ product is relieved by net reaction in the direction that consumes the added substance. How many times will the rate of the reaction 2 A + B → A 2 ​ B change if the concentration of substance A is doubled and that of substance B is halved?
