Suggest two materials other than hydrogen that can be used as fuels in fuel cells.
Fuel cells are voltaic cells in which the reactants are continuously supplied to the electrodes. They convert the energy from the combustion of fuels like Hydrogen, CO, Methane directly into electrical energy. Methane, oxygen, carbon monoxide and methanol can be used as fuels in fuel cells.
= 9 [ka2]
Hence, the rate of formation will increase by 9 times.
Vapour pressure of pure acetone and chloroform at 328 K are 741.8 mm Hg and 632.8 mm Hg respectively. Assuming that they form ideal solution over the entire range of composition, plot ptotal' pchloroform' and pacetoneas a function of xacetone. The experimental data observed for different compositions of mixture is.
100 ×xacetone |
0 | 11.8 | 23.4 | 36.0 | 50.8 | 58.2 | 64.5 | 72.1 |
pacetone /mm Hg |
0 | 54.9 | 110.1 | 202.4 | 322.7 | 405.9 | 454.1 | 521.1 |
pchloroform/mm Hg |
632.8 | 548.1 | 469.4 | 359.7 | 257.7 | 193.6 | 161.2 | 120.7 |
