Question

On increasing the pressure three fold, the rate of reaction of 2H2S+O2 xrightarrow products would increase : (A) 3 times (B) 9 times (C) 12 times (D) 27 times

Rate =kpH22s× pO2=x On increasing the pressure 3 fold Rate =k[3pH2s2]2[3po2] =k× 9H2s2× 3po2 =k× 27× pH2s2× po2=27x Hence, rate will increase 27 times.

Q. On increasing the pressure three fold, the rate of reaction of $2 H_{2} S + O_{2}$ products would increase :

3 times

9 times

12 times

27 times

Rate $= k p_{H}^{2}_{_{2} s \times p_{O_{2}}} = x$ On increasing the pressure 3 fold Rate $= k [3 p_{H_{2} s}^{2}]^{2} [3 p_{o_{2}}]$ $= k \times 9_{H_{2} s}^{2} \times 3 p_{o_{2}}$ $= k \times 27 \times p_{H_{2} s}^{2} \times p_{o_{2}} = 27 x$ Hence, rate will increase 27 times.
