At constant temperature and volume x decomposes as 2x (g)-3y(g)+2z(g)px is the partial pressure of x. Observation :1,2,3and time(min)0,100,200and px(in mm of Hg):800,400,200.i)What is the order of the reaction with respect to x? ii)Find the rate constant
iii)Find the total pressure when pressure of x is 700mmHg.
