An homogeneous ideal gaseous reaction $A{B}_{2\left(g\right)}?A_{\left(g\right)}+2B_{\left(g\right)}$  is carried out in a 25 litre flask at 27°C. The initial amount of AB₂ was 1 mole and the equilibrium pressure was 1.9atm. The value of K_p is x * 10^-2. The value of x is-----------. (Integer answer).

[R = 0.08206 dm³ atm K^-1 mol^-1]

The standard enthalpy of combustion at 25°C of hydrogen, cyclohexene (C₆H₁₀) and cyclohexane (C₆H₁₂) are –241, –3800 and –3920 kJ mol–1 respectively. Calculate the standard enthalpy of hydrogenation of cyclohexene.

HCP crystal is made of A ions and B ions are arranged in 2/3rd of octahedral voids. The simplest formula of compound is :-
