The reaction between hydrogen and iodine may be represented by the equation H2(g)+ I2(g) → 2HI(g), and is exothermic. Therefore
-
A.
an increase in temperature favours the forword reaction -
B.
an increase in pressure favours the backward reaction -
C.
both pressure and temperature muct be increased to favour the forward reaction -
D.
a decrease in temperature will favour the forward reaction -
E.
a decrease in pressure and an increase in temperature will favour the forward reaction
