An incorrect statement about equilibrium among the following is:

For the given reaction: H₂NCOONH₄ (s) \( \rightleftharpoons\) 2NH₃ (g) + CO₂ (g),
total pressure at equilibrium is found to be 18 atmospheres. The value of K_p for the above equilibrium will be 

1. 72 atm³

2. 144 atm³

3. 432 atm³

4. 864 atm³

The value of $∆\mathrm{H}$ for the reaction is less than zero. Formation of $X_2\left(g\right)$ $+$ $4$ $Y_2\left(g\right)$ $\leftrightharpoons 2X{Y}_4\left(g\right)$ will be favoured at:

The following equilibrium constants are given: 
N₂ + 3H₂ ⇌ 2NH₃; K₁ 
N₂ + O₂ ⇌ 2NO; K₂ 
H₂ + 1/2O₂ ⇌ H₂O; K₃ 

The equilibrium constant for the oxidation of NH₃ by oxygen to give NO is:

1. $K_2{K}_3^3/K_1$

2. $K_2{K}_3^2/K_1$

3. $K_2^2{K}_3/K_1$

4. $K_1{K}_2/K_3$ 

Hydrolysis of sucrose gives,

Sucrose + H₂O  $\leftrightharpoons$Glucose + Fructose

The equilibrium constant K_c for the reaction is 2 ×10¹³ at 300K. The value of ∆G^⊖ at 300K is-

1. – 5.64 ×10⁴ J mol^–1
2. – 7.64 ×10⁴ J mol^–1
3. – 6.64 ×10⁴ J mol^–1
4. – 8.64 ×10⁴ J mol^–1

For the equilibrium,

2NOCl(g) $\leftrightharpoons$2NO(g) + Cl₂(g)

the value of the equilibrium constant, K_c  is 3.75 × 10^–6 at 1069 K. 

The value of K_p for the reaction at this temperature is-

1. 0.048

2. 0.67

3. 0.29

4. 0.033

For the reaction, A+B $\rightleftharpoons$3C at 25$°$ C, a 3 litre vessel contains 1, 2, and 4 mole of A, B and C respectively. If K_c for the reaction is 10, then the reaction will proceed in:

1. forward direction                           

2. backward direction

3. in either direction                           

4. in equilibrium
