the work done when 6.5 g of zinc reacts with dil Hcl iss an open container at 298 K
Dear Madhumitha,I have already answered this eqn. plz check,moles of zinc = 6.5/65 = 0.1molWext. = – P*V = -1*V = -V => -nRT/P=> -0.1*0.0821*298/1=> -2.44658 Joules
No. Of moles= 6.5/65= 0.1mol. We know that Work in a chemical reaction can be calculated by this formula , W = -ngRT. W= -0.1mol*2Cal/K/Mol*298K =59.6 Calorie.
