The rate of a gaseous reaction is given by the expression k[A][B]. If ...
Concentration is number of moles per litre n/V . it is proportional to volume.

Rate of reaction is K[A][B] where [A] and [B] are a concentration of A and B.

When the volume is suddenly reduced to 1/4 times the original, the concentration changes 4 times the original concentration.

The new rate will be K[4A][4B] = 16K[A][B]
The new rate will be 16 times the original rate.

So, the correct answer is "16"...

The rate of a gaseous reaction is given by the expression k[A][B]. If ...
Explanation:

Given:
- Rate of reaction = k[A][B]
- Volume of reaction vessel reduced to 1/4

Effect of Volume Change on Rate:
- The rate of a reaction is directly proportional to the concentration of reactants.
- When the volume of the reaction vessel is reduced to 1/4, the concentrations of reactants [A] and [B] will increase by a factor of 4.

Effect on Rate Expression:
- Rate of reaction after volume change = k[4A][4B] = 16k[A][B]

Ratio of New Rate to Original Rate:
- New rate = 16 times the original rate
- Therefore, the reaction rate relating to the original rate will be 16.
Therefore, the correct answer is option 'D' (16).

Read the passage given below and answer the following questions:The rate of a reaction, which may also be called its velocity or speed, can be defined with relation to the concentration of any of the reacting substances, or to that of any product of the reaction. If the species chosen is a reactant which has a concentration c at time t the rate is - dc/dt, while the rate with reference to a product having a concentration x at time t is dx/dt. Any concentration units may be used for expressing the rate; thus, if moles per liter are employed for concentration and seconds for the time, the units for the rate are moles litre–1sec–1. For gas reactions pressure units are sometimes used in place of concentrations, so that legitimate units for the rate would be (mm. Hg) sec–1 and atm. sec–1 The order of a reaction concerns the dependence of the rate upon the concentrations of reacting substances; thus, if the rate is found experimentally to be proportional to the ath power of the concentration of one of the reactants A, to the both power of the concentration of a second reactant B, and so forth, via., rate = k CAα CAβ the over-all order of the reaction is simply n = α + β + ----- (2) Such a reaction is said to be of the αth order with respect to the substance A, the βth order with respect to B.In the following questions, a statement of Assertion followed by a statement of Reason is given. Choose the correct answer out of the following choices on the basis of the above passage.Assertion: Rate of reaction is a measure of change in concentration of reactant with respect to time.Reason: Rate of reaction is a measure of change in concentration of product with respect to time.
