One mole of solid Zn is placed in excess of dilute H_(2)SO_(4)" at "27^(@)C in a cylinder fitted with a piston. Find the value of DeltaE, q and w for the process if the area of piston is 500cm^(2) and it moves out by 50 cm against a pressure of 1 atm during the reaction. The heat given to surrounding is 36.5 KJ. Zn(s)+2H^(-)(aq)hArrZn^(2+)(aq)+H_(2)(g) |
| Answer» SOLUTION :`DeltaE=-39.03KJ//"MOLE",q=-36.5kJ:w=-2.53kJ` | |
