A) diminish to one-fourth of its initial value
B) diminish to one-eighth of its initial value
C) increase to eight times of its initial value
D) increase to four times of its initial value
Correct Answer: C
Solution :
Write the rate law equation for both cases and compare them. \[\left( \frac{dx}{dt} \right)=k{{[NO]}^{2}}\,[{{O}_{2}}]\] \[=k{{\left( \frac{{{n}_{NO}}}{V} \right)}^{2}}\left( \frac{{{n}_{{{O}_{2}}}}}{V} \right)\] \[\left( \frac{dx}{dt} \right)=\frac{k}{{{V}^{3}}}{{({{n}_{NO}})}^{2}}({{n}_{{{O}_{2}}}})\] ... (i) \[\left( \frac{dx}{dt} \right)=\frac{k\,{{({{n}_{NO}})}^{2}}({{n}_{{{O}_{2}}}})}{{{\left( \frac{V}{2} \right)}^{3}}}\] ?. (ii) From Eqs. (i) and (ii) \[\left( \frac{dx}{dt} \right)'=8\left( \frac{d\,x}{dt} \right)\]You need to login to perform this action.
