Question

1. The reaction 2NO(g)+H2(g) →N2O(g) +H20(g) follows the rate law. dp(N2O)/dt = k(Pno)²Ph2
If the reaction is initiated with PNo = 1000 mm Hg and pH, = 10 mm Hg, then the reaction will follow
(1) Third order kinetics
(2) Second order kinetics
(3) First order kinetics
(4) Zero order kinetics


Answer is First order kinetics just want explanation​

Answer 1

2No(q) + H2(g) ➝ N2O(g) + H2O(g)

the rate low of dp N2O/dt = k (pNO)² pH2

from the rate low it is evident that the patial order of then neartion with respect to NO is 2 and with respect to H2 is 1

so , overall order = 2+1

Answer: third order kinetics
