1(a) when 25.0ml of 0.500 mol.dm3 H2SO4(AQ) SOLUTION IS added to 0.025dm3 of 1.00 moldm3 KOH SOLUTION , THE TEMPERATURE OF THE REACTION MIXTURE RISES FROM 23.50 CELCIUS TO 30.17 CELCIUS . THE SPECIFIC HEAT CAPACITY AND DENSITY OF WATER 4.20j.g.celcius and 1.00 g.cm. the equation of the reaction is.
H2SO4 aq +2KOH aq =K2SO4 (aq) +2H2O
(I) IS THE REACTION ENDTHERMIC OR EXOTHERMIC? WHY?
(II) CALCULATE THE AMOUNT OF REACTANTS AVAILABLE (NUMBER OF MOLES) BEFORE THE REACTION . ARE THESE AMOUNTS IN A STOICHIOMETRIC(3sig. fig?
(iii) calculate the volume of water produced by the reaction and state whether it is significant or not if the overall volume of the reaction mixture is calculate with the correct number of decimal place . what is the total volume of the reaction mixture after the reaction is completed(3 sig.fig)?
(iv) calculate the amount of heat that was tranferred to the water(3 sig.fig)?
(V) calculate DH(DELTA H) THE ENTHALPY OF REACTION OF THIS NEUTRALISATION ( 3 SIG . FIG?
(VI) WHAT INCREASE OF TEMPERATURE WOULD BE OBSERVED IF 0.5 MOL OF SULPHURIC ACID REACTED WITH 1 MOL OF AQUEOUS POTASSIUM HYDROXIDE AND THE FINAL VOLUME OF THE REACTION MIXTURE WAS 1.0dm3?
