The vapour pressure of pure water at 25°c is 18 mm Hg . When a nonelectrolyte is dissolved, its vapour pressure becomes 17.32 mm Hg . What is the relative lowering of vapour pressure of the solution?

We have given, The vapour pressure of pure water at 25°C = 18mm Hg. After addition of non-electrolyte, the vapour pressure of water = 17.32 mm Hg. Then, lowering in vapour pressure = (18...

At constant temperature and pressure, two litres of hydrogen gas react with one litre of oxygen gas to produce two litres of water vapour.

(D) law of gaseous volumes \(\underset{2L}{H_2(g)}+\underset{2L}{O_2(g)}\longrightarrow \underset{2L}{H_2O(g)}\) Gay-Lussac's states that "At same temperature and pressure, when gases combine or produced in a chemical reaction, they do so in a simple ratio by volume. Here, \(H_2\), \(O_2\) and \(H_2O(g)\) are...

The ratio of molecular weight of hydrogen and oxygen in water is 1 : 8. (The relation between hydrogen and oxygen in linear

Correct option is (A) y = 8x \(\because\) Quantities of hydrogen and oxygen are x and y and their quantity are in ratio 1 : 8. \(\therefore\) x : y = 1 : 8 \(\Rightarrow\) \(\frac xy=\frac18\) \(\Rightarrow\) y =...

Equimolar mixture of two gases \( A_{2} \) and \( B_{2} \) is taken in a rigid vessel at temperature \( 300 K \). The gases reacts according to given equations : \[ \begin{array}{ll} A_{2}(g) \rightleftharpoons 2 A(g) & K_{P_{1}}=? \\ B_{2}(g) \rightleftharpoons & K_{P_{2}}=? \\ A_{2}(g)+B_{2}(g) & \rightleftharpoons 2 A B(g) & K_{P_{3}}=2 \end{array} \] If the initial pressure in the container was 2 atm and final pressure developed at equilibrium is \( 2.75 atm \). in which equilibrium partial pressure of gas \( A B \) was \( 0.5 atm \), calculate the ratio of \( \frac{ K _{ p _{2}}}{ K _{ p _{1}}} \). [Given : Degree of dissociation of \( B_{2} \) is greateı than \( A _{2} \) ].

this is the solution!!!!
