(i) 2SO_(2) (g) + O_(2) (g) overset(NO (g))to2SO_(3) (g) (ii) 2SO_(2) (g) overset(P (s)) to 2SO_(3) (g) (iii) N _(2)(g) + 3H_(2) (g) overset(Fe (s))to 2NH_(3) (g) (iv) CH_(3) COOCH_(3) (l) + H _(2) O (l) overset(HCl(l))to CH_(3) COOH (aq) + CH_(3) OH (aq)

Delta H for the reaction, SO_(2) (g) + (1)/(2) O_(2)(g) hArr SO_(3)(g) " " Delta H = -98.3kJ If the enthalpy of formation of SO_(3)(g) is -395.4kJ, then enthalpy of formation of SO_(2)(g) is:

Nitrogen tetraoxide (N_(2)O_(4)) decomposes as : N_(2) O_(4)(g) rarr 2NO_(2)(g) If the pressure of N_(2)O_(4) falls from 0.50 atm to 0.32 atm is 30 minutes the rate of appearance of NO_(2)(g) is :

At constant temperature in a litre vessel , when the reaction 2SO_(3)(g) iff 2SO_(2)(g) + O_(2)(g) is 2.25 litre "mol"^(-1) . What would be the concentration of Y at equilibrium with 2.0 moles of X and 3.0 moles of Z in one litre vessel ?

The reaction, 2SO_(2(g))+O_(2(g))leftrightarrowSO_(3(g)) is carried out in a 1 dm^(3) vessel and 2 dm^(3) vessel separately. The ratio of the reaction velocities will be
