Mixture (s) showing positive deviation from Raoult's law at `35^(@)C` is (are)

A

carbon tetrachloride + methanol

B

carbon disulphide + acetone

C

benzene + toluene

D

phenol +aniline

Text Solution

Verified by Experts

The correct Answer is:
A,B
(A) H-bonding of methanol breaks when `C CI_(4)` is added so bonds become weaker, resulting positive deviation.
(B) Mixing of polar and non-polar liquids will produce a solution of weaker interaction, resulting positive deviation.
(C) Ideal solution
(D) -ve deviation because stronger H-bond is formed.

A car from stationary state moves in positive X direction with constant acceleration 5 ms^(-2) for 8 s. Then it moves with constant velocity, then find the total distance covered by car after 12 s from the initial position.

In Exercise 14.9, let us take the position of mass when the spring is unstreched as x = 0, and the direction from left to right as the positive direction of x-axis. Give x as a function of time t for the oscillating mass if at the moment we start the stopwatch (t = 0), the mass is (a) at the mean position, (b) at the maximum stretched position, and (c) at the maximum compressed position. In what way do these functions for SHM differ from each other, in frequency, in amplitude or the initial phase?
