considering this given equation as 2NO + O2 --> 2NO2 this is believed to occur by the mechanism 2NO--> N2O2 k1,N2O2-->2NO k-1,N2O2+2-->2NO2 k2 derive the rate equation in terms of [NO] and [O2] as well as k ( Assume N2O2 to be in a steady state )
An unknown mass of each of the given substances 1.Sand (tf=70.4 C),2.Pyrex glass(tf=67.6 C),3.water(tf=55.9 C) ,4.ethanol (tf=45.9 C), initially at 19.0 degrees Celsius, absorbs 1930 Joules of heat. Find out the mass of each substance.
