Question

​20cc of CO2 are passed over red hot coke. the volume of CO evolved is? 1)10cc 2)20cc 3) 30cc 4) 40cc

Answer 1

Hey.

Here is your answer .

As the reaction is given by

CO2 + C -> 2CO

so, 1 volume of CO2 will give 2 Volume of CO
hence , 20cc of CO2 will give 2×20cc of CO

so, 40cc of CO will be evolved.

Thanks
