Question

28 g of $NO_{(g)}$ and 6 g of $\frac{1}{2}N_{2(g)} + \frac{1}{2}O_{2(g)}$ were kept at $Zn_{(s)} + Cu_{(aq)}^{2 +}$ in 1 litre vessel, the equilibrium mixture contained $Cu_{(s)} + Zn_{(aq)}^{2 +}$ of$C_{2}H_{5}OH_{(l)} + CH_{3}COOH_{(l)}$. The approximate value of $CH_{3}COOC_{2}H_{5(l)} + H_{2}O_{(l)}$ for the above reaction can be (in $COCl_{2(g)}$).

• A. 75
• B. 50
• C. 25
• D. 100

Answer 1

Answer: (A)

75

Answer 2

$721K$⇌$(K_{c})$

Initial conc. 1 3 0

at equilibrium 1-0.81 3-2.43 1.62

0.19 0.57

No. of moles of $0.5M$mole

No. of moles of $K_{p}$mole

No. of moles of $50/RT$mole

$K_{p} > K_{c}$=75
