The heat output and the accumulation of monobromomalonic acid during chemical oscillation in the bromate, malonic acid, sulphuric acid and catalyst [Ce(III), Mn(II), Fe(phen)32+, Ru(dipy)32+] systems were measured and the results interpreted. The behaviour of the reacting oscillating systems depends to a certain extent on the catalyst applied. Both the rate of heat evolution and the rate of accumulation of monobromomalonic acid are periodic. The heat of the cerium-catalysed Belousov oscillating reaction is 130±5 kJ mol-1 bromate.
