Select the option which is correct regarding true//false of the given stateements:
Statements-1: Thermal decomposition of solid `CaCO_(3)` is expected to be spontaneous as high temperature and non-spontaneous at low temperatures. Statements-2: If the rate law for an acid catalysed reaction is `r=K(Reactant)^(1)[Catalyst]^(@)` then rate will be independent of presence / absence of catalyst.
Statement-3: When water freezes in a glass beaker, volumes of the system increases at constant temperature and hence entropy will also increses.
