QUESTION: 19
The rate of a gaseous reaction is given by the expression k [A][B]. If the volume of the reaction vessel is suddenly reduced to 1/4th of the initial volume, the reaction rate relting to original rate will be
Solution: R=k[A][B]
[Concentration]=moles/volume
moles is constant and volume is reduced to V/4
R=k[n1/V][n2/V]
R2=k[n1/(V/4)][n2/(V/4)]
R2=16R1
R2/R1=16
