Question:
In which of the following chemical equations, the abbreviations represent the correct states of the reactants and products involved at reaction temperature ?
(a) H2(l) + O2(l) ———–> 2H2O(g)
(b) H2(g) + O2(l) ———>2H2O(l)
(c) 2H2(g) + O2(g) ———> 2H2O(l)
(d) 2H2(0) + O2(g) ——–> 2H2O(g)
Solution:
(d). The reaction is carried upon strong heating. At this temperature, H2O formed is in gaseous state.
