When the mixture is homogeneous
F = M x A
F = 0.25 x 196
F = 49 N
Work for a irreversible reaction, in thermodynamics, is calculated by multiplying the external pressure with the change in volume. Therefore,
Work = P ( V2 - V1 )
Work = 1.02 (1.403 - 0.055)
Work = 1.375 L-atm
Hope this answers the question. Have a nice day.
I have written the answer in the comments i hope it will be helpful to you ......
