In a first order reaction, the concentration of reactant decrease from 400 mol L^(-1) to 25 mol L^(-1) in 200 seconds. The rate constant for the reaction is

Calculate the pressure excerted by 5 mol of CO_(2) in 1 L vessel at 47^(@)C using van der Waals equation. Also report the pressure of gas if it behaves ideally in nature. (a=3.592 atm L^(2) mol^(-2), b=0.0427 L mol^(-1))

A quantity of 2 mol of NH_(3) occupies 5L at 27^(@)C . Calculate the pressure of the gas using the van der Waals equation if a = 4.17 "atm "L^(2)" mol"^(-2) and b = 0.3711 L "mol"^(-1) .

A vessel of 25 L capacity contains 10 mol of steam under 50 bar pressure. Calculate the temperature of steam using van der Waals equation if for water : a="5.46 bar L"^(2)"mol"^(-2) and b="0.031 L mol"^(-1) .

The van der Waal's constants for a gas are a=1.92 atm L^(2) "mol"^(-2),b=0.06 L "mol"^(-1) . If R = 0.08 L atm K^(-1) "mol"^(-1) , what is the Boyle's temperature (in K) of this gas ?

For a first order reaction, it takes 5 minutes for the initial concentration of 0.6 mol L^(-1) to become 0.4 mol L^(-1) . How long in all will it take for the initial concentration to become 0.3 mol L^(-1) ?
