The function, which is NOT an eigenfunction of the indicated operator, is

1.0 mol of perfect monatomic gas is put through the cycle shown in the figure. The total work (in J) done during the Cycle is.

(Use 1L-bar = 100 J, R = 8.3 J K^-1 mol^-1 = 0.083 L-bar K^-1 mol^-1, ln 2 = 0.7)

If the rate constant for a base catalyzed ester hydrolysis reaction is 0.20 L mol^-1 s^-1, half-life (in s) of the ester(Given [ester]₀ = [base]₀ = 0.05 mol. L^-1) would be closed to

The expected number of  bands in the IR spectra of fac-[Mo(PPh₃)₃(CO)₃] and trans- [Mo(PPh₃)₂(CO)₄] are, respectively

A liquid of density 1.1 gm cm^-3 climbs to a height of 5.0 cm when a capillary with internal radius of 0.2 mm is dipped into it. The surface tension (in Nm^-1) of the liquid is closest to
