Predict the effect of decreasing the temperature on the amounts of products in t

Question

Predict the effect of decreasing the temperature on the amounts of products in the following reactions. (NOTE: Only TWO submissions are allowed for this question.) (a) C0(g) + 2 H2(g)-CH3OH(g) Horxn =-90.7 k O The amount of product will increase. The amount of product will decrease. O The amount of product will not change. (b) C(s) + H2O(g)-CO(g) + H2(g) Honn = 131 k The amount of product will increase O The amount of product will decrease. O The amount of product will not change. (c) 2 NO2(g)2 NO(g)+02(9) (endothermic) O The amount of product will increase. O The amount of product will decrease. The amount of product will not change. (d) 2 C(s) + O2(g) 2 CO(g) (exothermic) O The amount of product will increase. O The amount of product will decrease. The amount of product will not change.

Explanation / Answer

Endothermic reactions are favoured at high temperatures

exothermic reactions are favoured at low temperature

a.The reaction is exothermic therefore reducing the temperature will increase the amount of products(amount of products will increase)

b.Reaction is endothermic therefore by decreasing the temperature the amount of products will decrease

C.as the reaction is endothermic the amount of products will decrease

d.as the reaction is exothermic the amount of products will increase
