At 373 K, a gaseous reaction A → 2B + C is found to be of first order. Starting with pure A, the total pressure at the end of 10 min was 176 mm of Hg and after a long time when A was completely dissociated, it was 270 mm of Hg. The pressure of A at the end of 10 minutes was
Text Solution
Verified by ExpertsThe correct answer is:
B
A 
2 B + C
t = 0 P 0 0 0 P 0
t = t (P O – x) 2x x P 0 + 2x = 176
0 2 P 0 P 0 3 P 0 = 270 P 0 = 90
2 x = 176 – 90 = 86
x = 43
Pressure of A after 10 minute = 90 – 43 = 47
