Consider the reaction : 2H_(2) (g) + O_(2) (g) hArr2H_(2)O (g) When hyudrogen is ignited in the presence of oxygen, a lot of heat is released and water is produced. At room temperature, the DeltaH_(r xx n)^(@) is about -484 k J//mol and Delta S_(r xx n)^(@) is about -87 kJ/mol. Given this data how would you interpet this thermodynamic process ? Select the correct answer:

consider the reaction . 2H_(2)(g)+2NO(g)to N_(2)(g)+2H_(2)O(g) The rate low of this reaction will be ,if mechanism of reaction is Step1: 2NOhArrN_(2)O_(2)["fast equilibrium"] Step2: N_(2)O_(2)+H_(2)toN_(2)O+H_(2)O["slow"] Step3: N_(2)O+H_(2)toN_(2)+H_(2)O["fast"]

Consider the reaction, C_(6)H_(12)O_(6)(g)+6O_(2)(g) to 6CO_(2)(g) +6H_(2)O(l) , which of the following expressions is /are correct?

Consider the reaction: a, 6CO_(2)(g)+6H_(2)O(l)rarr C_(6)H_(12)O_(6)(aq)+6O_(2)(g) b. O_(3)(g)+H_(2)O_(2)(l) rarr H_(2)O(l)+2O_(2)(g) Why it is more appropriate to write these reaction as: a. 6CO_(2)(g)+12H_(2)O(l) rarr C_(6)H_(12)O_(6)(aq)+6H_(2)O(l)+6O_(2)(g) O_(3)(g)+H_(2)O_(2)(l) rarr H_(2)O(l)+O_(2)(g)+O_(2)(g) also suggest a technique to investigate the path of the above (a) abd (b) redox reactions.
