Question

x + 2 y + 3 z = 2 w For the above reaction, the rate of reaction is given as follows: R ( in M / min ) = 100 [ x ] 2 − [ x ] [ z ] 70 [ w ] 2 ​ If initially each of the reactant has concentration 1 M and initially there is no D present then find the value of 99 R . Where, R= Rate of reaction when Molar mass of mixture is 86.67% of initial molar mass of mixture.
