Suppose CO2 (g) and CO (g) are brought into contact into C(s) at 1000K where the partial pressures of carbon dioxide and carbon monoxicde are 2.00 atm and 0.50 atm, respectively. Is the reaction described by the following equation at equilibrium? if not, in which direction will the reaction proceed to attain equilibrium?
C(s) + CO2(g) +2CO(g) <---->Kp=1.90atm
What is the reason for using a phase transfer catalyst? a)It is used to transfer the catalyst to the active site of the reaction b)It serves as a proton transfer agent which moves protons from a base to an acid c)It is a small molecule which attac..
