The partial pressure of \( CH_3OH(g) \), \( CO(g) \), and \( H_2(g) \) in an equilibrium mixture for the reaction:

\[ CO(g) + 2H_2(g) \rightleftharpoons CH_3OH(g) \]

are 2.0, 1.0, and 0.1 atm respectively at \( 427^\circ C \). The value of \( K_p \) for the decomposition of \( CH_3OH \) to \( CO \) and \( H_2 \) is:

The shape of \([ \text{Cu}(\text{NH}_3)_4 ]^{2+}\) is:

The limiting equivalent conductivity of NaCl, KCl, and KBr are \( 126.5 \), \( 150.0 \), and \( 151.5 \) S cm\(^2\) eq\(^{-1}\), respectively. The limiting equivalent ionic conductivity for Br\(^{-}\) is \( 78 \) S cm\(^2\) eq\(^{-1}\). The limiting equivalent ionic conductivity for Na\(^+\) ions would be:

The conjugate base of \( (\text{CH}_3)_2\text{NH}_2^+ \) is:

An ideal gas expands against a constant external pressure of 2.0 atmosphere from 20 litre to 40 litre and absorbs 10 kJ of heat from the surrounding. What is the change in internal energy of the system? (given: \( 1 \, {atm-litre} = 101.3 \, {J} \))

200 mL of an aqueous solution of a protein contains 1.26 g. The osmotic pressure of this solution at 300 K is found to be \( 2.57 \times 10^{-3} \, {bar} \). The molar mass of the protein will be: (R = 0.083 L bar mol\(^{-1}\) K\(^{-1}\))
