In Ostwalds process for the manufacture of nitric acid, the. first step involves the oxidation of ammonia gas by oxygen. gas to give nitric oxide gas and steam. What is the maximum weight of nitric oxide that, can be obtained starting only with '10.00 g' of ammonia and '20.0 g' of oxygen?

Name the catalyst used in i) the oxidation of ammonia to nitric acid by Ostwald'process. ii) the synthesis of ammonia by Haber process.

4 g of copper was dissolved in concentrated nitric acid. The copper nitrate solution on strong heating gave 5 g of its oxide. The equivalent weight of copper is

0.324 g of copper was dissolved in nitric acid and the copper nitrate so produced was burnt till all copper nitrate converted to 0.406 g of copper oxide. Calculate the equivalent weight of copper.

A metal oxide hás thẻ formula 'Al_2 O_3' . It can be reduced by hydrogen to give free metai and water. 0.1596g of this metal oxide requires 6 mg of hydrogen for complete reduction. What is the atomic weight of metal?

Nitrogen combines with oxygen to form nitric oxide: N_2(g)+O_2(g) hArr 2NO(g) , Delta H=+80 kJ mol^(-1) The decomposition of NO(g) is favoured by : decrease in the pressure, increase in pressure, decrease in temperature, increasing the concentration of N_2

The rate of formation of nitric oxide (NO) in the following reaction is 3.6 xx 10^(-3) (molL)^(-1) (s)^(-1) 4NH_(3)(g)+5 O_(2) (g) harr 4 NO(g)+ 6 H_(2) O(g) Find the rate of disappearance of oxygen.

A welding fuel gas contains carbon and hydrogen only. Burning a small sample of î in oxygen gives 3.38 g carbon dioxide, 0.690 g of water and no other products. A volume of 10.0 L (measured at STP) of this welding gas is found to weigh 11.6 g. Calculate (i) empirical formula, (ii) molar mass of the gas, and (iii) molecular formula.

Dihydrogen gas is obtained from natural gas by partial oxidation with steam as per following endothermic reaction: 'C H_4(g)+H_2 O_(g) hArr C O_(g)+3 H_2(g)' a) Write an expression'for 'K_p' for the above reaction. b) How will the values of 'K_p' and composition of equilibrium mixture be affected by i) increasing the pressure ii) increasing the temperature iii) using a catalyst.
