Read the information below to identify the features of the experiment.

Sandstone contains sand (mainly silicon dioxide) and calcium carbonate. Excess sandstone was reacted with dilute hydrochloric acid. 

CaCO3s+2HClaq→CaCl2aq+H2Ol+CO2g. The rate of the reaction was measured during the mass lost during the reaction.

When carbon monoxide and steam are passed over a heated iron catalyst they react as follows:

COg+H2Og⇌CO2g+H2g

The forward reaction is exothermic and backward reaction is endothermic. Predict, using the information about the experiment, the effect on the yield of hydrogen caused by increasing the quantity of steam.
