Given that the reaction 2 H2(g) + O2(g) → 2 H2O(g) is exothermic, which of the following is true of the reaction 2 H2O(g) → 2 H2(g) + O2(g) ?
Its activation energy is lower than that of 2 H2(g) + O2(g) → 2 H2O(g).
+
Its activation energy is the same as that of 2 H2(g) + O2(g) → 2 H2O(g).
Its activation energy is higher than that of 2 H2(g) + O2(g) → 2 H2O(g).
There is no relationship between its activation energy and that of 2 H2(g) + O2(g) → 2 H2O(g).

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
