raising the temperature of the reaction mixture the formation of additional hydrogen gas the formation of less hydrogen gas no effect on the quantity of hydrogen gas

Explanation / Answer

PartA

no effect on the quantity of hydrogen gas

C is solid so changing the carbon will not increase the equilibrium of the reaction.

PartB

the formation of additional hydrogen gas

by increasing the concentration of H2O farward reaction will favour so more H2 will produce.

PartC

the formation of additional hydrogen gas

sice it is the endo thermic reaction raising the temperature will favour the farward reaction so more hydrogen gas will produce.
