Be sure to answer all parts. predict the effect of decreasing the temperature on the amounts of reactants in the following reactions: (a) c2h2(g) + h2o(g) ⇌ ch3cho(g) δh o rxn = −151 kj the amounts of reactants stay the same. the amounts of reactants decrease. the amounts of reactants increase. (b) ch3ch2oh(l) + o2 (g) ⇌ ch3co2h(l) + h2o(g) δh o rxn = −451 kj the amounts of reactants stay the same. the amounts of reactants decrease. the amounts of reactants increase. (c) 2 c2h4(g) + o2(g) ⇌ 2 ch3cho(g) (exothermic) the amounts of reactants stay the same. the amounts of reactants decrease. the amounts of reactants increase. (d) n2o4(g) ⇌ 2 no2(g) (endothermic) the amounts of reactants decrease. the amounts of reactants stay the same. the amounts of reactants increase.
