Tre elementary isomerization exolhermic reacion

$A=B$

is carnec out isothermally al $400K$ in a PBR in whicr pressure drpp plays a role, with $=0\mathrm{.}001k{g}^{-1}.$

Currently, $50\%$ conversion is achieved. The equitorium constant at this temperature is $3\mathrm{.}0.$

a$.$ For a flxed mass flow rate in$,$ it the reactor clameter is increasec by a factor of $4,$ the conversion

insufficiert information to tell

b$.$ Tor a fixed mass flow rate $m^{},$ the equilibrium conversion is

$(1)x_s=0\mathrm{.}5(2)x_s=0\mathrm{.}667(3)x_s=0\mathrm{.}75(4)$ insufficient information to tell

c$.$ For a fixed mass flow rate $m^{},$ if the reactor diameter is incressed by a factor of $2,$ the equilibrium conversion $x,$ will

$(1)$ increase $(2)$ decrease $(3)$ remain the same $(4)$ insufficient information to tell

d$.$ For a fixed mass flow rate $m^{},$ if the partisle size is increased, the ecuilibrium conversion will

$(1)$ increase $(2)$ decrease $(3)$ remain the same $(4)$ insufficient information to tell

e$.$ For a fixed mass flow rate $i,$ if the particle size is increased, the ccoversion will

increase $(2)$ decrease $13)$ remain the same $(4)$ insuffcent informaticn to tell
