Calculate the work done when 50 g of iron is dissolved in HCl at 25^(@)C in (i) a cloed vessel and (ii) an open beaker when the atmospheric pressure is 1atm.
For the reaction, A(s) + 3B(g) rarr 4C(g) + d(l) Delta H and Delta U are related as :
Calculate the work done in the following reaction at 50^(@)C . State whether work is done on the system or by the system. SO_(2(g))+(I)/(2)O_(2(g))rarrSO_(3(g))
Calculate the work done for the vaporisation of 1 mole of water in calories :-(1 atm, 100^(@)C )
A picece of zinc of mass 5.0 g is dropped into a beaker of dilute hydrochloric acid. Calculate the work done by the system (mangnitude only in J) as a result of the reaction. The atmospheric pressure is 1.1 atm and temperture 23^(@) C.
Calculate the work done when 56g of iron reacts with hydrochloric acid in (a) a closed vessel of fixed volume and (b) an open beaker at 25^(@)C .
For the reaction 2A(g)+3B(l)rarrC(g)+4D(l),DeltaH=300"cal//mol" Calculate DeltaU (in calories) of reaction when 3 moles of A (g) react with 4 moles of B (l) at 27^(@)C. (R=2"cal//mol"-K)
A strip of magnesium of mass 15 g is droped into an opean beaker of dilute hydrochloric acid. Calculate the work done by the system as a result of reaction. The atmospheric pressure is 1.0 atm and temperature is 25^(@)C . Also calculate the work done if the reaction is carried out in closed beaker.
