For decomposition of Ag_(2)O into 2 mol of Ag(s) and 1//2 mol of O_(2)(g) . The heat absorbed is 30.66 J , when the process is carried out at constant volume. The process is carried out at constant volume. The value of DeltaH of process is

For a process H_(2)O(s) rarr H_(2)O(l) at 273 K

H_(2)O_(2)to H_(2)O+O_(2) the rate most of this reaction is 2xx10^(-2)"min"^(-1) (at certain temp.) & reaction is started with 0.5M conc. of H_(2)O_(2) , after 23.03 min the reaction was suddenly stopped by lowering the temp & the remaining H_(2)O_(2) was completely reacted with NaCl . If no. of moles of O_(2) produced in second reaction is 1/a find a. (log1.5=0.2)

Assertion : For the change, H_(2)O_((l))rarr H_(2)O_((s)),DeltaH=DeltaU . Reason : No enthalpy change is involved in this process.

Assertion :- At constant pressure for the change H_(2)O(s)rarr H_(2)O(g) work done is nwgative. Reason :- During phase transition work done is always negative.
