$\text{ψ}=Nr(6\text{–}Zr)e^{-Zr/3}cos\theta$, is a proposed hydrogenic wavefunction, where $Z$ = Atomic number, $r$ = radial distance from the nucleus, $\theta$ = azimuthal angle, $N$ is a constant. The INCORRECT statement about $\text{ψ}$ is

The van der Waals constants a and b of CO2 are 3.64 $L^2$ bar $mo{l}^{-2}$ and 0.04 L $mo{l}^{-1}$, respectively. The value of R is 0.083 bar $d{m}^3$ $mo{l}^{-1}$ $K^{-1}$. If one mole of $C{O}_2$ is confined to a volume of 0.15 L at 300 K, then the pressure (in bar) exerted by the gas, is ______________

A plot of osmotic pressure against concentration (g $L^{-1}$) of a polymer is constructed. The slope of the plot

A platinum electrode is immersed in a solution containing 0.1 M $F{e}^{2+}$ and 0.1 M $Fe63+$. Its potential is found to be 0.77 V against SHE. Under standard conditions and considering activity coefficients to be equal to unity, the potential of the electrode, when the concentration of $Fe3+$ is increased to 1 M, is

Molybdenum crystallizes in a bcc structure with unit cell dimensions of 0.314 nm. Considering the atomic mass of molybdenum to be 96, its density (in kg $m^{-3}$) is
