C https://www.webassign.net/web/Student Alllylllllt in the following Predict the effect of increasing the temperature on the amounts of products 90.7 kJ CH30H(g) (a) cog) 2 H2(g) O The amount of product will decrease The amount of product will increase. O The amount of product will not change. 131 kJ co(g) H2(g) (b) c(s) H20(g) The amount of product will decrease. O The amount of product will increase. The amount of product will not change. (c) 2 NO2 (g) 2 NO(g) o2(g) (endothermic) The amount of product will decrease. The amount of product will increase. The amount of product will not change. (d) 2 c(s) o2(g) 2 co(g) (exothermic The amount of product will decrease. The amount of product will increase. The amount of product will not change.Explanation / Answer
(a) This is an exothermic reaction (value of delta H is -ve) which means heat is released during the course of the reaction. If we increase the temperature, the reaction will try to counteract the change according to Le chatelier principle. As, in the forward reaction heat is produced the reaction will be favored in the reverse direction and amount of product formed will decrease.
(b) This is an endothermic reaction. By increasing the temperature the reaction will be favored in the forward direction and amount of product will increase.
(c) Again , this is an endothermic reaction. By increasing the temperature the reaction will be favored in the forward direction and amount of product will increase.
(d) This is an exothermic reaction. By increasing the temperature the reaction will be favored in the reverse direction and amount of product will decrease.
