Some Basic Concepts Of Chemistry Question 252

Question: An electric discharge is passed through a mixture containing 50 c.c. of $O_{2}$ and 50 c.c. of $H_{2}$ . The volume of the gases formed (i) at room temperature and (ii) at 1100C will be

Options:

A) (i) 25 c.c. (ii) 50 c.c.

B) (i) 50 c.c. (ii) 75 c.c.

C) (i) 25 c.c. (ii) 75 c.c.

D) (i) 75 c.c. (ii) 75 c.c.

Show Answer

Answer:

Correct Answer: C

Solution:

At room temperature $2 H_{2 (g)} + O_{2 (g)} \to 2 H_{2} O_{(l)}$

t =0 50ml 50ml 0 t =t 50 ? 2x 50 ? x 2x =0 25gases (50)liquid In this case $H_{2}$ is limiting reagent x = 25ml At 110°C $2 H_{2 (g)} + O_{2 (g)} \to 2 H_{2} O_{(g)}$ $V_{g a s} = 75, m l$

t =t 0 25ml 50ml
