For a chemical reaction A + B $?$ C + D

$\left({\Delta }_r{H}^{\Theta }=80kJmo{l}^{-1}\right)$ the entropy change ${\Delta }_r{S}^{\Theta }$ depends on the temperature T (in K) as ${\Delta }_r{S}^{\Theta }=2T\left(J{K}^{-1}mo{l}^{-1}\right).$

Minimum temperature at which it will become spontaneous is-------------K. (Integer)

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 :-

Enthalpy of neutralisation of CH₃COOH by NaOH is – 50.6 kJ/mol and the heat of neutralisation of a strong acid with NaOH is – 55.9 kJ/mol. The value of ΔH for the ionisation of CH₃COOH is :
