A) 3 times
B) 9 times
C) 12 times
D) 27 times
Correct Answer: D
Solution :
Rate \[=kp{{_{H}^{2}}_{_{2}s\times {{p}_{{{O}_{2}}}}}}=x\] On increasing the pressure 3 fold Rate\[=k{{[3p_{{{H}_{2}}s}^{2}]}^{2}}[3{{p}_{{{o}_{2}}}}]\] \[=k\times 9_{{{H}_{2}}s}^{2}\times 3{{p}_{{{o}_{2}}}}\] \[=k\times 27\times p_{{{H}_{2}}s}^{2}\times {{p}_{{{o}_{2}}}}=27x\] Hence, rate will increase 27 times.
