Question

The reaction
2N, O2(g) → 4NO2(g) + O2(g)
is first order with respect to N2O5.
Which of the following graph would yield a straight
line :-
(1) log(PN,0.) v/s time with negative slope
(
(2) Pr,o,' v/s time
(3) PN,O, v/s time
(4) log(PN,0.) v/s time with positive slope​

Answer 1

Explanation:

For a first order reaction, the graph of logarithm of the partial pressure of reactant to the time is a straight line with negative slope. 

Hence, logpN2O5 vs time t will give a straight line.
