For the decomposition reaction NH2COONH4 (s) 2NH3 (g) + CO2 (g), Kp = 2.9 × 10-5 atm3.

What will be the total pressure of gases at equilibrium, when 1.0 mol of NH
2COONH4 (s) was taken to start with?

 
0.0194 atm
0.0388 atm
0.0582 atm
0.0776 atm

Directions: In the following question a statement of Assertion is given followed by a corresponding statement of Reason just below it. Of the statement mark the correct answer as:

(a) If both assertion and reason are true and the reason is the correct explanation of the assertion.
(b) If both assertion and reason are true but the reason is not the correct explanation of the assertion.
(c) If assertion is true statement but reason is false.
(d) If both assertion and reason are false.

Assertion: On mixing 500 mL of 10-6 M Ca2+ ion and 500 mL of 10-6 M F-1 ion, the precipitate of CaF2 will be obtained. Ksp (CaF2 = 10-18).
Reason: If Ksp is greater than ionic product, a precipitate will develop.

 
(a)
(b)
(c)
(d)
