Question

In haber's process rate of formation of ammonia is 1.7kg/hr. calculate rate of consumption of H2 in g/m​?

Answer 1

Answer:

2.55 kg/h=255/6g/m

This q is completely based on Rate law of chemical kinetics. Points to remembered every time you solve these type of questions

• Reactants form product,thus rate of change of concentration of reactants is negative as its decreasing.To make it positive as rate is always positive we put -sign multiplied with dR/dt.
• No of moles taken that is stoichiometric coefficient ,say mis divided by dC/dt if in balanced chemical reaction if mC occurs as reactants(with negative sign) and positive if in product.
• aA+bB->cC+did
• -dR/dt=dP/dt
• -dA/dt1/a=-dB/dt.1/b=dC/dt.1/c=dD/dt.1/d Using above and maths got answer.
