(A) True: According to the rate law,the rate of reaction is directly proportional to the concentration of reactants. Thus,decreasing the concentration decreases the rate.
$(b)$ False: The conversion of graphite to diamond is a thermodynamically favorable process but kinetically extremely slow,taking millions of years.
$(c)$ False: Corrosion of iron (rusting) is a very slow process occurring over a long period.
$(d)$ True: The term 'kinesis' is derived from the Greek word meaning 'movement' or 'motion'.
