$CN^-$ is strong field ligand. This is due to the fact that

Which one of the following statements about the zeolites is false ?

The rate of first order reaction is $1.5 \times 10^{-2}$ mol $L^{-1} \, min^{-1}$ at 0.5 M concentration of the reactant. The half-life of the reaction is

The rapid change of $pH$ near the stoichiometric point of an acid base titration is the basis of indicator detection. $pH$ of the solution is related to ratio of the concentrations of the conjugate acid ($HIn$) and base $ (In^-) $ forms of the indicator given by the expression

The following ratio is generally constant for a species

An electric dipole has the magnitude of its charge as $q$ and its dipole moment is $p$. It is placed in a uniform electric field $E$. If its dipole moment is along the direction of the field, the force on it and its potential energy are respectively

Consider a system of two particles having masses $m_1$ and $m_2$. If the particle of mass $m_1$ is pushed towards the mass centre of particles through a distance '$d$', by what distance would be particle of mass $m_2$ move so as to keep the mass centre of particles at the original position ?

A mass of $0.5 \,kg$ moving with a speed of $1.5 \,m/s$ on a horizontal smooth surface, collides with a nearly weightless spring of force constant $k = 50 \,N/m$. The maximum compression of the spring would be
