Answer : The molecular weight of a gas is, 128.9 g/mole
Explanation : Given,
Density of a gas = 5.75 g/L
First we have to calculate the moles of gas.
At STP,
As, 22.4 liter volume of gas present in 1 mole of gas
So, 1 liter volume of gas present in mole of gas
Now we have to calculate the molecular weight of a gas.
Formula used :
Now put all the given values in this formula, we get the molecular weight of a gas.
Therefore, the molecular weight of a gas is, 128.9 g/mole
Answer:
The dimerization of butadiene to 4-vinylcyclohexene folows second order kinetics and its rate law will be given by :
Explanation:
The rate of the reaction ;
As given in the question , that graph of time verses was linear but plots of
or
was curved.
Generally:
Graph of time verses for zero order reaction is linear with negative slope.
Graph of time verses for secon order reaction is linear with negative slope.
Graph of time verses for secon order reaction is linear with positive slope.
So, the dimerization of butadiene to 4-vinylcyclohexene folows second order kinetics and its rate law will be given by :
