Consider the following reaction: CO(g)+2H2(g)-->CH3OH(g) Kp=2.26*10^4 at 25 degrees C. Calculate deltaGrxn under each of the following conditions: At STP, at Equilibrium, and when PCH3OH=1.1 atm, and pCO=pH2=1.3*10^-2 atm. Please do all three and show me the steps! I'm really struggling with this.
A buffer is composed of 0.400 mol H2PO4^- and 0.400 mol HPO4^2- diluted with water to a volume of 1.00 L. The pH of the buffer is 7.210. How many moles of HCl must be added to decrease the pH to 6.210?
