In this reaction, how does the rate of forward reaction vary with the concentration of the product? 2h2s(g) ⇌ 2h2(g) + s2(g) it increases with an increase in the concentration of s2(g). it decreases with a decrease in the concentration of h2(g). it increases with a decrease in the concentration of h2(g). it decreases with an increase in the concentration of s2(g). it decreases with increase in the concentration of h2(g). multiple answers

C) It increases with a decrease in the concentration of . D) It decreases with increase in the concentration of .

Explanation: According to Le Chatelier's principle, if an equilibrium reaction is disturbed, the reaction would try to undo the change imposed.

Thus if the concentration of the products in increased, the reaction would shift in a direction where the concentration of products is decreasing i.e in backward direction.

If the concentration of the products in decreased, the reaction would shift in a direction where the concentration of products is increasing i.e in forward direction.

When the concentration of either of the products, i.e or is increased, the reaction will shift in backward direction and the rate of forward direction decreases.

rosa was looking for patterns to predict the products of chemical reactions. she recorded three similar decomposition reactions in the table.she should record 2licl + 3o2.

in the last row of the table. it is the thermal decomposition of chlorate lithium, hence, she should record these products as: lithium chloride ( 2licl ) and oxygen ( 3o2 )   2 > 2 licl + 3o2.
